Object cycles should not prevent allocation elimination/sinking
https://bugs.webkit.org/show_bug.cgi?id=143073

Reviewed by Filip Pizlo.

Source/JavaScriptCore:

This patch introduces a new allocation sinking phase that is able to
sink cycles, in DFGAllocationCycleSinkingPhase.cpp. This phase
supersedes the old allocation sinking phase in
DFGObjectAllocationSinkingPhase.cpp, as that previous phase was never
able to sink allocation cycles while the new phase sometimes can; see
DFGAllocationCycleSinkingPhase.cpp for details.

For now, the new sinking phase is kept behind a
JSC_enableAllocationCycleSinking flag that reverts to the old sinking
phase when false (i.e., by default). This also removes the old
JSC_enableObjectAllocationSinking flag. run-javascriptcore-tests
defaults to using the new sinking phase.

Reviewed by Michael Saboff.

This changes register naming conventions in the llint and baseline JIT
in order to use as few (native) callee-save registers as possible on
64-bits platforms. It also introduces significant changes in the way
registers names are defined in the LLint and baseline JIT in order to
enable a simpler convention about which registers can be aliased that
is valid across all architecture, and described in

[iOS WK2] When choosing an initial viewport scale, take overflow on the <body> into account
https://bugs.webkit.org/show_bug.cgi?id=146918
rdar://problem/9222837

Reviewed by Tim Horton.

Use as input to the viewport scaling algorithm a contents size from the FrameView
that takes overflow on the viewport renderer into account. This prevents unexpected
viewports scaling on pages that have content that overflows their expressed contents size,
but apply overflow to the <body>.

Source/WebCore:

page/FrameView.cpp:

(WebCore::FrameView::contentsSizeRespectingOverflow): Look for overflow:hidden on each axis of
the m_viewportRenderer, which is computed post-layout by calculateScrollbarModesForLayout()
and is used for scrollbar logic on OS X. Clip unscaledDocumentRect on each axis, and then
apply page scale.

Source/WebKit2:

WebProcess/WebPage/WebPage.cpp:

(WebKit::WebPage::mainFrameDidLayout): Use contentsSizeRespectingOverflow(),
rather than raw contentsSize(), to determine scaling.

If Watchpoint::fire() looks at the state of the world, it should definitely see its set invalidated, and maybe it should see the object of interest in the transitioned-to state
https://bugs.webkit.org/show_bug.cgi?id=146897

Reviewed by Mark Lam.

The idea is to eventually support adaptive watchpoints. An adaptive watchpoint will be
able to watch for a condition that is more fine-grained than any one watchpoint set. For
example, we might watch a singleton object to see if it ever acquires a property called
"foo". So long as it doesn't have such a property, we don't want to invalidate any code.
But if it gets that property, then we should deoptimize. Current watchpoints will
invalidate code as soon as any property is added (or deleted), because they will use the
transition watchpoint set of the singleton object's structure, and that fires anytime
there is any transition.

An adaptive watchpoint would remember the singleton object, and when it got fired, it
would check if the object's new structure has the property "foo". If not, it would check
if the object's new structure is watchable (i.e. has a valid transition watchpoint set).
If the property is missing and the structure is watchable, it would add itself to the
watchpoint set of the new structure. Otherwise, it would deoptimize.

There are two problems with this idea, and this patch fixes these problems. First, we
usually fire the transition watchpoint before we do the structure transition. This means
that if the fire() method looked at the singleton object's structure, it would see the old
structure, not the new one. It would have no way of knowing what the new structure is.
Second, inside the fire() method, the watchpoint set being invalidated still appears
valid, since we change the state after we fire all watchpoints.

This patch addresses both issues. Now, in the most important case (addPropertyTransition),
we fire the watchpoint set after we have modified the object. This is accomplished using
a deferral scope called DeferredStructureTransitionWatchpointFire. In cases where there is
no deferral, the adaptive watchpoint will conservatively resort to deoptimization because
it would find that the singleton object's structure is no longer watchable. This is
because in the absence of deferral, the singleton object would still have the original
structure, but that structure's watchpoint set would now report itself as having been
invalidated.

[GTK] Contents not correctly laid out when the web view is not realized
https://bugs.webkit.org/show_bug.cgi?id=142532

Reviewed by Darin Adler.

The problem is that we are not reporting any size until the web
view is realized, so any web view loaded in a separate tab in the
browser, will report 0x0 as the window.innerWidth,
window.innerHeight until the view is realized. Websites that use
the window.innerWidth/innerHeight during the page load to decide
how to lay out the contents will be rendered wrongly.
I haven't been able to reproduce this with unit tests, as this
requires the particular case of same window but different web
views using tabs for example.

UIProcess/API/gtk/PageClientImpl.cpp:

(WebKit::PageClientImpl::viewSize): Always report the drawing area
size to make usre it's in sync with the WebProcess page size.

UIProcess/API/gtk/WebKitWebViewBase.cpp:

(webkitWebViewBaseSizeAllocate): Remove the optimization of only
report the size when it has changed, since both the redirected
window and the drawing area already do that check. Also remove the
optimization of waiting until the view is mapped to report its
size, since that's often too late for websites using the window
size during load.
(webkitWebViewBaseMap): Never report size on map, it should have
already been reported by size-allocate.

Watchpoints should be removed from their owning WatchpointSet before they are fired
https://bugs.webkit.org/show_bug.cgi?id=146895

Reviewed by Sam Weinig.

This simplifies the WatchpointSet API by making it so that when Watchpoint::fire() is
called, the Watchpoint is no longer in the set. This means that you don't have to remember
to remove it from the set's list (currently we do that implicitly as part of whatever
any particular Watchpoint::fireInternal() does), and you can now write adaptive
watchpoints that re-add themselves to a different set if they determine that the thing
they are actually watching is still intact but now needs to be watched in a different way
(like watching for whether some singleton object has a property of some name).

bytecode/Watchpoint.cpp:

(JSC::Watchpoint::~Watchpoint): Add a comment about why this is necessary.
(JSC::Watchpoint::fire): Make this out-of-line, private, and make it assert that we're no longer on the list.
(JSC::WatchpointSet::fireAllWatchpoints): Make this remove the watchpoint from the list before firing it.

bytecode/Watchpoint.h:

(JSC::Watchpoint::fire): Deleted. I moved this to Watchpoint.cpp.
