[REGRESSION][ftlopt merge][32-bit] stress/prune-multi-put-by-offset-replace-or-transition-variant.js.dfg-eager hits an assertion in SpeculativeJIT::silentSavePlanForGPR
​https://bugs.webkit.org/show_bug.cgi?id=135323

Reviewed by Oliver Hunt.

SpeculativeJIT::silentSavePlanForGPR likes to believe that if a node is a constant,
then it's a constant that can be represented using that node's current DataFormat.
This doesn't work if the constant had been filled as a JSValue, and then one of the
fillSpeculateBlah() methods had speculated that it's of some type that the constant
isn't. Unless fillSpeculateBlah() specifically defends against this case, we'll have
a constant that claims to have a contradictory data format.

This patch fixes such a bug in the 32-bit fillSpeculateCell(). The 64-bit
fillSpeculateCell() appears to not have this bug, but I added a similar defense
mechanism anyway just in case, since this is one of those mistakes that keeps
reappearing.

[WK2] Crash when accessing window.localStorage after calling window.close()
​https://bugs.webkit.org/show_bug.cgi?id=135328
<rdar://problem/17315237>

Reviewed by Sam Weinig.

Source/WebCore:
Fixes an issue where accessing local storage for the first time after calling window.close()
causes a crash.

For now, we should disallow accessing local storage after calling window.close() regardless of
whether it's the first access to local storage as this seems like a bad idiom to support. Note,
this represents a change in behavior from WebKit1. If such usage of window.localStorage turns
out to be reasonable then we can visit this decision again in <​https://bugs.webkit.org/show_bug.cgi?id=135330>.

  • page/DOMWindow.cpp:

(WebCore::DOMWindow::localStorage): Modified to only return the cached local storage or
create a new local storage so long as the page isn't being closed. Also, substitute nullptr
for 0.
(WebCore::DOMWindow::close): Call Page::setIsClosing() to mark that the page is closing.

  • page/Page.cpp:

(WebCore::Page::Page): Initialize m_isClosing to false.

  • page/Page.h:

(WebCore::Page::setIsClosing): Added.
(WebCore::Page::isClosing): Added.

LayoutTests:
Added test by Andy Estes, LayoutTests/storage/domstorage/localstorage/access-storage-after-window-close.html,
to ensure that we don't crash when accessing local storage for the first time after calling window.close().

Additionally added tests that ensure that updates to local storage are ignored after calling
window.close() regardless of whether local storage was accessed before the call to window.close().

Web Inspector: debugger should be able to show variable types

Reviewed by Filip Pizlo.


Increase the amount of type information the VM gathers when directed
to do so. This initial commit is working towards the goal of
capturing, and then showing (via the Web Inspector) type information for all
assignment and load operations. This patch doesn't have the feature fully
implemented, but it ensures the VM has no performance regressions
unless the feature is specifically turned on.

Structure bit fields should have a consistent format

Currently we use C-style bit fields for a number of member variables in Structure to save space.
This makes it difficult to load these fields in the JIT. We should instead use our own bitfield
format to make it easy to load and test these variables in JIT code.

We don't use them for anything. We'll replace them with a generic CellType type for all
the objects that are JSCells, aren't JSObjects, and for which we generally don't care about
their JSType at runtime.

[ftlopt] PutStructure and PhantomPutStructure shouldn't leave the world in a clobbered state
​https://bugs.webkit.org/show_bug.cgi?id=134002


Reviewed by Mark Hahnenberg.


The effect of this bug was that if we had a PutStructure or PhantomPutStructure then any
JSConstants would be in a Clobbered state, so we wouldn't take advantage of our knowledge
of the structure if that structure was watchable.


Also kill PhantomPutStructure.

Crash in Web Content Process under ~PDFDocument under clearTouchEventListeners at topDocument()
​https://bugs.webkit.org/show_bug.cgi?id=135319
<rdar://problem/17315168>

Reviewed by Darin Adler and Antti Koivisto.

  • WebProcess/WebCoreSupport/WebFrameLoaderClient.cpp:

(WebKit::WebFrameLoaderClient::committedLoad):
Allow data through to WebCore for frames with custom content providers;
the only custom content provider currently implemented is main frame PDF
on iOS, which will end up creating a PDFDocument in WebCore, which drops all
data on the floor immediately, so this won't result in WebCore doing anything
with the data, but makes sure that more of the normal document lifecycle is maintained.

In the future, we might want to consider ensuring that all custom content providers
end up creating a SinkDocument or something similarly generic to ensure that
WebCore doesn't try to do anything with their data, but for now, the only client is covered.

  • dom/Document.h:
  • dom/Document.cpp:

(WebCore::Document::Document):
(WebCore::Document::prepareForDestruction):
Add a flag on Document, m_hasPreparedForDestruction, which ensures
that each Document only goes through prepareForDestruction() once.
prepareForDestruction() can be called a number of times during teardown,
but it's only necessary to actually execute it once.

This was previously achieved by virtue of all callers of prepareForDestruction()
first checking hasLivingRenderTree, and prepareForDestruction() tearing down
the render tree, but that meant that prepareForDestruction() was not called
for Documents who never had a render tree in the first place.

The only part of prepareForDestruction() that is now predicated on hasLivingRenderTree()
is the call to destroyRenderTree(); the rest of the function has the potential to be relevant
for non-rendered placeholder documents and can safely deal with them in other ways.

It is important to call prepareForDestruction() on non-rendered placeholder documents
because some of the cleanup (like disconnectFromFrame()) is critical to safe destruction.

  • loader/FrameLoader.cpp:

(WebCore::FrameLoader::clear):
Call prepareForDestruction() even if we don't have a living render tree.
For the sake of minimizing change, removeFocusedNodeOfSubtree still
depends on having a living render tree before calling prepareForDestruction().

  • page/Frame.cpp:

(WebCore::Frame::setView):
(WebCore::Frame::setDocument):
Call prepareForDestruction() even if we don't have a living render tree.

Web Inspector: Timelines performance is very slow, has many forced layouts

Patch by Joseph Pecoraro <Joseph Pecoraro> on 2014-07-26

  • UserInterface/Views/NavigationItem.js:

(WebInspector.NavigationItem):
(WebInspector.NavigationItem.prototype.get hidden):
(WebInspector.NavigationItem.prototype.set hidden):
Don't have the parent navigation bar update layout if the hidden state did not change.
This greatly reduces the number of forced layouts as timeline nodes are added.

  • UserInterface/Views/NavigationSidebarPanel.js:

(WebInspector.NavigationSidebarPanel.prototype.showEmptyContentPlaceholder):
(WebInspector.NavigationSidebarPanel.prototype.hideEmptyContentPlaceholder):
Don't do any work if this is not changing the view.

(WebInspector.NavigationSidebarPanel.prototype._updateContentOverflowShadowVisibilitySoon):
(WebInspector.NavigationSidebarPanel.prototype._updateContentOverflowShadowVisibility):
(WebInspector.NavigationSidebarPanel.prototype._treeElementAddedOrChanged):
When first selecting a specific timeline (Layout / Scripts) we would have a very long hang
updating the content. Most of this was time spent updating the overflow shadow visibility
because every single tree element addition was causing a layout invalidation and forced layout.
Coalesce all of the tree element adds into a single update at the end.

  • UserInterface/Views/TimelineOverview.js:

(WebInspector.TimelineOverview.prototype.updateLayout):
Calculating the visible duration checks offsetLeft. Calculate this once, outside
of a loop down below, to prevent or reduce possible forced layouts.

  • UserInterface/Views/TreeOutline.js:

(TreeElement.prototype.revealed):
Prevent doing any work for timeline tree elements outside of the selected time range.
Previously they were considered revealed if a parent was expanded, even though that
parent was hidden. This greatly reduces the amount of work during a recording, since
previously we were potentially doing a forced layout for hidden nodes.

  • UserInterface/Views/TimelineSidebarPanel.js:

(WebInspector.TimelineSidebarPanel.prototype.treeElementForRepresentedObject.looselyCompareRepresentedObjects):
Ignore ProfileNode, which may happen here in the Script timeline.

Increase the amount of type information the VM gathers when directed
to do so. This initial commit is working towards the goal of
capturing, and then showing (via the Web Inspector) type information for all
assignment and load operations. This patch doesn't have the feature fully
implemented, but it ensures the VM has no performance regressions
unless the feature is specifically turned on.

This also adds pruning of PutStructure, since I basically had no choice but
to implement such logic within MultiPutByOffset.

Subpixel rendering: Rounded rect gets non-renderable at certain subpixel size.

<rdar://problem/17812921>

Reviewed by Tim Horton.

While calculating the rounded rect for painting, the radius is adjusted to compensate
for the pixel snapped size. However while scaling the radius, certain values overflow
(float) mantissa and it produces a non-renderable rounded rect where the radius becomes bigger
than the rectangle dimensions. In such cases, we need to shrink the radius to make it
renderable again.

Source/WebCore:
Test: media/media-source/media-source-end-of-stream-buffered.html

When determining the correct ReadyState for the MediaSource in monitorSourceBuffers(), use the same
definition of "buffered" as is used in the calculation of HTMLMediaElement.buffered and in the
Stream Ended algorithm. Namely, when the stream has ended, treat each SourceBuffer as if its last
buffered range extends to the duration of the stream. This allows playback to continue through to
the duration without stalling due to monitorSourceBuffers().

[iOS] REGRESSION(r171526): Images fail to load sometimes
​https://bugs.webkit.org/show_bug.cgi?id=135304
<rdar://problem/17811922>

Reviewed by Alexey Proskuryakov.

SharedBuffer::createCFData() calls data() as a way to coalesce the data array elements and
segments into m_buffer. However, data() has an optimization where if we had a single element
in the data array, it would just return that and not do coalescing. So when we passed
m_buffer to WebCoreSharedData, we passed a buffer with no data in it.

Fix this by bringing the optimization to createCFData() and return the CFDataRef from the
data array if we just have a single element.

No new tests. Should be covered by existing tests.

[MSE] High CPU usage in SampleMap::findSamplesWithinPresentationRange() with a large number of buffered samples.

Reviewed by Geoffrey Garen.

Anchor our search for overlapping frames to the end of the search range when the overlap range is sufficiently
close to the end of the search range. The common case for this search is when a sample is about to be appended
to the end of the sample queue, so this should turn most searches into no-ops.

[ftlopt] Fold constant Phis
​https://bugs.webkit.org/show_bug.cgi?id=133967


Reviewed by Mark Hahnenberg.


It's surprising but we didn't really do this before. Or, rather, we only did it
incidentally when we would likely crash if it ever happened.


Making this work required cleaning up the validater a bit, so I did that too. I also added
mayExit() validation for nodes that didn't have origin.forExit (i.e. nodes that end up in
the Phi header of basic blocks). But this required beefing up mayExit() a bit.

[ftlopt] Get rid of NodeDoesNotExit and also get rid of StoreEliminationPhase
​https://bugs.webkit.org/show_bug.cgi?id=133985


Reviewed by Michael Saboff and Mark Hahnenberg.


Store elimination phase has never been very profitable, and now that LLVM can do dead
store elimination for us, this phase is just completely pointless.


This phase is also the primary user of NodeDoesNotExit, which is a flag that the CFA
computes. It computes it poorly and we often get bugs in it. It's also a lot of code to
maintain.


This patch does introduce a new mayExit() calculator that is independent of the CFA and
should be enough for most of the previous NodeDoesNotExit users. Currently it's only used
for assertions in the DFG backend, but we could use it if we ever brought back any of the
other optimizations that previously relied upon NodeDoesNotExit.


This is performance-neutral, except for SunSpider, where it's a speed-up.

[ftlopt] DFG should use its own notion of JSValue, which we should call FrozenValue, that will carry around a copy of its structure

The impetus for this was to provide some sense and reason to race conditions arising from
cell constants having their structure changed on the main thread - this is harmess because
we defend against it, but when it goes wrong, it can be difficult to reproduce because it
requires a race. Giving the DFG the ability to "freeze" a cell's structure fixes this.


But this patch goes quite a bit further, and completely rationalizes how the DFG reasons
about constants. It no longer relies on the CodeBlock constant pool at all, which allows
for a more object-oriented approach: for example a Node that has a constant can tell you
what constant it has without needing a CodeBlock.

32-bit builds currently break because global variable IDs for high

Source/JavaScriptCore:
This patch splits for-in loops into three distinct parts:

  • Iterating over the indexed properties in the base object.
  • Iterating over the Structure properties in the base object.
  • Iterating over any other enumerable properties for that object and any objects in the prototype chain.


It does this by emitting these explicit loops in bytecode, using a new set of bytecodes to
support the various operations required for each loop.

This patch splits for-in loops into three distinct parts:

  • Iterating over the indexed properties in the base object.
  • Iterating over the Structure properties in the base object.
  • Iterating over any other enumerable properties for that object and any objects in the prototype chain.


It does this by emitting these explicit loops in bytecode, using a new set of bytecodes to
support the various operations required for each loop.

REGRESSION (r169105): Crash in selection
​https://bugs.webkit.org/show_bug.cgi?id=134303

Patch by Radu Stavila <​stavila@adobe.com> on 2014-07-24
Reviewed by David Hyatt.

Source/WebCore:

When splitting the selection between different subtrees, all subtrees must have their selection cleared before
starting to apply the new selection. Otherwise, when selecting objects in a named flow thread and going up
its containing block chain, we can end up in the view's selection root, which has not yet been updated and so
we get inconsistent data.

To achieve this goal, the selection update was split into a "clear" and an "apply" method. The updateSelectionForSubtrees
method first iterates through all subtrees and performs the "clear" method and then starts all over again
and performs the "apply" method.

REGRESSION(r164401): Placing a caret doesn't bring up autocorrection panel
​https://bugs.webkit.org/show_bug.cgi?id=135278

Reviewed by Tim Horton.

The bug was caused by editorUIUpdateTimerFired calling respondToChangedSelection only if the selection was
triggered by dictation instead of only if it was NOT triggered by dictation.

Prior to r164401, AlternativeTextController::respondToMarkerAtEndOfWord exited early when SetSelectionOptions
had DictationTriggered set. r164401 intended to move this check to editorUIUpdateTimerFired to avoid passing
options around but the boolean condition was erroneously flipped.

Fixed the bug by negating the condition in editorUIUpdateTimerFired.

No new tests for now since autocorrection panel cannot be tested automatically. (We should really automate this!)

(WebKit::WebPage::dynamicViewportSizeUpdate):
There is no guarantee that the main frame have its root view when performing a dynamicViewportSizeUpdate(),

The odd part for me is <rdar://problem/17804891> is a little too frequent. In the vast majority of cases,
there is a RenderView, it seems actually pretty hard not to have one on dynamicViewportSizeUpdate().

Skipping hit testing is safe because it is a completely optional part of this algorithm.
When the hit test is not done, the new position is computed based on the relative position prior to
the size change.

The call to didCommitLayerTree() can cause one or two visible rect updates,
via changes to the UIScrollView contentSize and contentOffset. As a result, we
would notify the scrolling tree about a viewport change, but using the old
scrolling tree rather than the new one, so we could move layers around for
nodes which are about to be removed from the tree.

However, we also have to ensure that programmatic scrolls are applied after
didCommitLayerTree() has updated the view size, so have RemoteScrollingCoordinatorProxy
store data about programmatic scrolls and return them to the caller, which
can apply them after didCommitLayerTree().

Fixes an issue where cookies may be created in the wrong cookie store.

Currently, when we update the CFURLRequest object associated with a ResourceRequest object
we explicitly set a cookie storage, cookie accept policy, and SSL properties based on the
corresponding values in the old CFURLRequest object (if we have one). This ultimately leads
to CFNetwork associating the cookies for the request with a different cookie store when we
handle the request in the NetworkProcess. Instead, we shouldn't set these properties
explicitly as we already copy them implicitly earlier (via CFURLRequestCreateMutableCopy()).

Source/WebKit2:
In some cases, a fixed or sticky positioned layer would end up at its position corresponding to the WebProcess
instead of sticking the to real viewport in the UIProcess.

The sequence of event is:
1) A layer becomes fixed in some ScrollingTree transaction.
2) Later, some change in the WebProcess causes a LayerTree update for that exact same layer, but no corresponding

ScrollingTree update is made.

3) In the UIProcess, the position of the fixed layer is changed due to the LayerTree update.

But! There is no ScrollingTree change, updateScrollingTree() never sets fixedOrStickyLayerChanged to true,
and the position is not corrected.

-> The layer is now at the wrong position until the next VisibleContentRectUpdate.

Ideally, we should have fixedOrStickyLayerChanged track if either the position or size of a fixed layer changed
in the layer tree. This is tricky since the layer tree does not keep track of the fixed nodes of the scrolling tree.

Since this complexity seems risky at this point, I went for something simpler but with more overhead:
any time the scrolling tree contains either a fixed or sticky layer, viewportChangedViaDelegatedScrolling()
is called to "fix" the position.

JSWrapperMap's jsWrapperForObject() needs to defer GC.
<​https://webkit.org/b/135258>

Reviewed by Oliver Hunt.

In the process of creating a JS wrapper, jsWrapperForObject() will create
the prototype and constructor of the corresponding ObjC class, as well as
for classes in its inheritance chain. These prototypes and constructors
are stored in Weak references in the JSObjCClassInfo objects. During all
the allocation that is being done to create all the prototypes and
constructors as well as the wrapper objects, a GC may occur thereby
collecting one or more of these newly created prototype and constructor
objects.

One example of where this problem can manifest is in wrapperForObject()
which is called from jsWrapperForObject(). In wrapperFoObject(), we do
the following steps:

  1. reallocateConstructorAndOrPrototype() which creates the prototype object and store it in JSObjCClassInfo's m_prototype which is a Weak ref.
  2. makeWrapper() to create the wrapper object, which may trigger a GC. GC will collect the prototype object and nullify the corresponding JSObjCClassInfo's m_prototype Weak ref.
  3. call JSObjectSetPrototype() to set the JSObjCClassInfo's m_prototype in the newly created wrapper. This results in the wrapper getting a jsNull as a prototype instead of the expected prototype object.

To ensure that the prototype and constructor objects are retained until
they can be referenced properly from the wrapper object,
jsWrapperForObject() should defer GC until it's done with its work.

Sharing SharedBuffer between WebCore and ImageIO is racy and crash prone
​https://bugs.webkit.org/show_bug.cgi?id=135069
<rdar://problem/17470655>

Reviewed by Simon Fraser.

When passing image data to ImageIO for decoding, we pass an NSData subclass that is a wraper
around SharedBuffer. This can be a problem when ImageIO tries to access the data on the CA
thread. End result is data corruption on large image loads and potential crashes. The fix is
to have SharedBuffer create a copy of its data if the data has been passed to ImageIO and
might be accessed concurrently.

Since Vector is not refcounted, we do this by having a new refcounted object in SharedBuffer
that contains the buffer and we pass that in our NSData subclass WebCoreSharedBufferData.
Code that would result in the Vector memory moving e.g. append(), resize(), now checks to
see if the buffer was shared and if so, will create a new copy of the vector. This ensures
that the main thread does not end up invalidating the vector memory that we have passed it
to ImageIO.

Make improvements to Type Profiling
​https://bugs.webkit.org/show_bug.cgi?id=134860

Patch by Saam Barati <​sbarati@apple.com> on 2014-07-23
Reviewed by Filip Pizlo.

I improved the API between the inspector and JSC. We no longer send one huge
string to the inspector. We now send structured data that represents the type
information that JSC has collected. I've also created a beginning implementation
of a type lattice that allows us to resolve a display name for a type that
consists of a single word.

I created a data structure that knows which functions have executed. This
solves the bug where types inside an un-executed function will resolve
to the type of the enclosing expression of that function. This data
structure may also be useful later if the inspector chooses to create a UI
around showing which functions have executed.

Better type information is gathered for objects. StructureShape now
represents an object's prototype chain. StructureShape also collects
the constructor name for an object.

Expression ranges are now zero indexed.

Removed some extraneous methods.

On pages which size their document to the device size, the WKContentView size
never changes after it's created. In this situation, we never set a bounds

on all enclosed UIScrollViews for overflow:scroll.

Fix by making the _rootContentView and the _inspectorIndicationView use autosizing
so they are always the size of their parent view, and remove the explicit setting

[iOS][WK2] r171124 is incorrect when the virtual keyboard is up
​https://bugs.webkit.org/show_bug.cgi?id=135187

Patch by Benjamin Poulain <​bpoulain@apple.com> on 2014-07-23
Reviewed by Simon Fraser.

Unfortunately, restricting the input into the document rect does not work.
When the keyboard is up, the keyboard bounds can overlap the WKWebView, and
the valid range should account for that.

Instead of playing with the keyboard rect, we can limit the scroll position
inside the valid range of UIScrollView. The keyboard always adjusts the UIScrollView
range as needed to give access to the content. Using that range is a bit more permissive
because the page could scroll to reveal content in the content inset defined by the client
of the API (this could actually be quite useful for hybrid apps).

There was already a function to change the content offset in the valid scrollview
range: changeContentOffsetBoundedInValidRange(), I extracted the range check
to contentOffsetBoundedInValidRange() for the needs of -[WKWebView _scrollToContentOffset:].

So...contentOffsetBoundedInValidRange() is cool, but it is not in the right coordinate
system. The scroll position we get from the WebProcess is in document coordinates, while
contentOffsetBoundedInValidRange() works with the UIScrollView coordinates.
To fix that, we scale the input position to get to the same scale as UIScrollView, then
apply the insets with the weirdly named [WKWebView _adjustedContentOffset:].

REGRESSION (r171376): Sometimes we detect less than the whole phone number
​https://bugs.webkit.org/show_bug.cgi?id=135220
<rdar://problem/17783423>

Reviewed by Brady Eidson.

  • editing/Editor.cpp:

(WebCore::Editor::scanSelectionForTelephoneNumbers):
Use the visible selection's start and end instead of base and extent, because they'll
always be in the right order in the case of a directional selection (base can be *after* extent
if you select from right to left). This fixes the code that expands the selection.

Pass the *entire* expanded selection to DataDetectors, instead of using TextIterator.
This way, we will find each number only once, and will never get part of a phone number once
and then the whole phone number later.

nodes which are about to be removed from the tree.

[ftlopt] Phantoms in SSA form should be aggressively hoisted
​https://bugs.webkit.org/show_bug.cgi?id=135111

Reviewed by Oliver Hunt.

In CPS form, Phantom means three things: (1) that the children should be kept alive so long
as they are relevant to OSR (due to a MovHint), (2) that the children are live-in-bytecode
at the point of the Phantom, and (3) that some checks should be performed. In SSA, the
second meaning is not used but the other two stay.

The fact that a Phantom that is used to keep a node alive could be anywhere in the graph,
even in a totally different basic block, complicates some SSA transformations. It's not
possible to just jettison some successor, since tha successor could have a Phantom that we
care about.

This change rationalizes how Phantoms work so that:

1) Phantoms keep children alive so long as those children are relevant to OSR. This is true

in both CPS and SSA. This was true before and it's true now.


2) Phantoms are used for live-in-bytecode only in CPS. This was true before and it's true

now, except that now we also don't bother preserving the live-in-bytecode information
that Phantoms convey, when we are in SSA.


3) Phantoms may incidentally have checks, but in cases where we only want checks, we now

use Check instead of Phantom. Notably, DCE phase has dead nodes decay to Check, not
Phantom.


The biggest part of this change is that in SSA, we canonicalize Phantoms:

  • All Phantoms are replaced with Check nodes that include only those edges that have checks.


  • Nodes that were the children of any Phantoms have a Phantom right after them.


For example, the following code:

5: ArithAdd(@1, @2)
6: ArithSub(@5, @3)
7: Phantom(Int32:@5)


would be turned into the following:

5: ArithAdd(@1, @2)
8: Phantom(@5) @5 was the child of a Phantom, so we create a new Phantom right after

@5. This is the only Phantom we will have for @5.

6: ArithSub(@5, @3)
7: Check(Int32:@5) We replace the Phantom with a Check; in this case since Int32: is

a checking edge, we leave it.


This is a slight speed-up across the board, presumably because we now do a better job of
reducing the size of the graph during compilation. It could also be a fluke, though. The
main purpose of this is to unlock some other work (like CFG simplification in SSA). It will
become a requirement to run phantom canonicalization prior to some SSA phases. None of the
current phases need it, but future phases probably will.

Web Inspector: InspectorBackend's promise-based agent API does not support multiple return values
​https://bugs.webkit.org/show_bug.cgi?id=135207

Reviewed by Joseph Pecoraro.

Source/WebInspectorUI:
The promise wrapper implementation assumed that the protocol callback supplies a single 'payload'
return value, but InspectorBackend will actually unpack multiple return values as multiple
callback arguments. Set a special flag so it will not try to apply multiple return values.

It would read better if multiple return values could be spread to the resolve callback, but
multiple argument support are not required by the Promises specification, so we won't use them.

ASSERTION FAILED: generatingElement() in WebCore::RenderNamedFlowFragment::regionOversetState
​https://bugs.webkit.org/show_bug.cgi?id=135153

Reviewed by David Hyatt.

Source/WebCore:
Even though the CSSRegions spec defines the behaviour of a multicolumn region,
we currently do not support this functionality. This patch ensures that a multicolumn
element does not become a region. In the future, when we will implement the multicolumn
as region functionality, ​http://dev.w3.org/csswg/css-regions/#multi-column-regions, we
will remove this restriction.

REGRESSION (r169105): Crash in selection
​https://bugs.webkit.org/show_bug.cgi?id=134303

Reviewed by David Hyatt.

Source/WebCore:

When splitting the selection between different subtrees, all subtrees must have their selection cleared before
starting to apply the new selection. Otherwise, when selecting objects in a named flow thread and going up
its containing block chain, we can end up in the view's selection root, which has not yet been updated and so
we get inconsistent data.

To achieve this goal, the selection update was split into a "clear" and an "apply" method. The updateSelectionForSubtrees
method first iterates through all subtrees and performs the "clear" method and then starts all over again
and performs the "apply" method.

Also, the selectionStart/End members in RenderView have been renamed to fix problems caused by the fact that
RenderView inherits SelectionSubtreeRoot, which also has the same selectionStart/End members.
