REGRESSION(r190717): [GTK] Popup menus stop working after being dismissed without selecting an item
https://bugs.webkit.org/show_bug.cgi?id=152977

Reviewed by Michael Catanzaro.

This happens since r190717 when you open a popup menu and without
selecting any option it's dismissed (press ESC or click somewhere
else). This is because I removed the code to track when the menu
is unmapped, thinking that it was no longer necessary. But we need
to send the DidChangeSelectedIndexForActivePopupMenu to the
WebProcess with -1 as index to keep the web process in sync.

run-jsc-stress-tests should try to figure out a JSC path
https://bugs.webkit.org/show_bug.cgi?id=152971

Reviewed by Yusuke Suzuki.

This patch now allows run-jsc-stress-tests to be run
without a "--jsc <jsc-path>" argument. It tries
to take its best guess at a <jsc-path> automagically.

This makes it much easier to just run run-jsc-stress-tests
with a directory or a yaml file as an argument.
You now just do this:
run-jsc-stress-tests <path-to-yaml>
or
run-jsc-stress-tests <path-to-directory-of-js-files>

I wrote this patch because I'd often find myself hacking the
run-javascriptcore-tests file just to run a particular subset of tests.
Because I always forget the arguments to run-jsc-stress-tests (which means
I always forgot to provide a --jsc argument), I always found it easier to
just hack on that file instead of calling run-jsc-stress-tests directly.
No longer is this true!

Web Inspector: Storage tab navigation bar should fit on a single line
https://bugs.webkit.org/show_bug.cgi?id=152473

Patch by Devin Rousso <Devin Rousso> on 2016-01-11
Reviewed by Timothy Hatcher.

The wrapping of the navigation bar on the Storage tab was caused by the
fact that Sidebar.js used a minimum width of 200px, regardless of the
content within the sidebar (unless it had a NavigationBar). Logic has
been added that causes the sidebar to use the selected panel's own
minimum width calculation if it is greater than 200px.

Use a profile to store allocation structures for subclasses of InternalFunctions
https://bugs.webkit.org/show_bug.cgi?id=152942

Reviewed by Michael Saboff.

This patch adds InternalFunctionAllocationProfile to FunctionRareData, which holds
a cached structure that can be used to quickly allocate any derived class of an InternalFunction.
InternalFunctionAllocationProfile ended up being distinct from ObjectAllocationProfile, due to
constraints imposed by Reflect.construct. Reflect.construct allows the user to pass an arbitrary
constructor as a new.target to any other constructor. This means that a user can pass some
non-derived constructor to an InternalFunction (they can even pass another InternalFunction as the
new.target). If we use the same profile for both InternalFunctions and JS allocations then we always
need to check in both JS code and C++ code that the profiled structure has the same ClassInfo as the
current constructor. By using different profiles, we only need to check the profile in InternalFunctions
as all JS constructed objects share the same ClassInfo (JSFinalObject). This comes at the relatively
low cost of using slightly more memory on FunctionRareData and being slightly more conceptually complex.

Additionally, this patch adds subclassing to some omitted classes.

Make it easier to introduce exotic instructions to Air
https://bugs.webkit.org/show_bug.cgi?id=152953

Reviewed by Benjamin Poulain.

Currently, you can define new "opcodes" in Air using either:

1) New opcode declared in AirOpcode.opcodes.
2) Patch opcode with a new implementation of Air::Special.

With (1), you are limited to fixed-argument-length instructions. There are other
restrictions as well, like that you can only use the roles that the AirOpcode syntax
supports.

With (2), you can do anything you like, but the instruction will be harder to match
since it will share the same opcode as any other Patch. Also, the instruction will have
the Special argument, which means more busy-work when creating the instruction and
validating it.

This introduces an in-between facility called "custom". This replaces what AirOpcode
previously called "special". A custom instruction is one whose behavior is defined by a
FooCustom struct with some static methods. Calls to those methods are emitted by
opcode_generator.rb.

The "custom" facility is powerful enough to be used to implement Patch, with the caveat
that we now treat the Patch instruction specially in a few places. Those places were
already effectively treating it specially by assuming that only Patch instructions have
a Special as their first argument.

This will let me implement the Shuffle instruction (bug 152952), which I think is needed
for performance work.

Turn Check(true) into Patchpoint() followed by Oops
https://bugs.webkit.org/show_bug.cgi?id=152968

Reviewed by Benjamin Poulain.

This is an obvious strength reduction to have, especially since if we discover that the
input to the Check is true after some amount of B3 optimization, then stubbing out the rest
of the basic block unlocks CFG simplification opportunities.

It's also a proof-of-concept for the Check->Patchpoint conversion that I'll use once I
implement sinking (bug 152162).

[JSC] When resolving Stack arguments, use addressing from SP when addressing from FP is invalid

Patch by Benjamin Poulain <bpoulain@apple.com> on 2016-01-11
Reviewed by Mark Lam.

ARM64 has two kinds of addressing with immediates:
-Signed 9bits direct (really only -256 to 255).
-Unsigned 12bits scaled by the load/store size.

When resolving the stack addresses, we easily run
past -256 bytes from FP. Addressing from SP gives us more
room to address the stack efficiently because we can
use unsigned immediates.

Instead of relaxing on subclasses of RefCounted<T>, relax on subclasses of RefCountedBase.
This allows e.g NeverDestroyed<CSSPrimitiveValue> to relax its pointee despite the class

[GTK] Cleanup RenderThemeGtk
https://bugs.webkit.org/show_bug.cgi?id=152888

Reviewed by Michael Catanzaro.

Use a common path for GTK+ 3.19 and previous versions, simplifying
the code and removing a lot of ifdefs.

createStyleContext() now receives a theme part enum value, and an optional parent GtkStyleContext. It encapsulates all the differences between GTK+ 3.19 and previous version leaving the rendering code common and free of ifdefs.
Stock icons support have been removed, simplifying the code that now always renders symbolic icons, updating the colors depending on the current state.
Media button and colors have been removed, because they are unused now that we render the media controls with CSS.
ComboBox separators support has also been removed. In GTK+ 3.19 combo boxes no longer have separators and most of the GTK+ themes don't use the either, so it's better to simple not render them anymore in WebKit either.
Code to paint caps lock indicator has been removed too, since caps lock indicator is now shadow dom and automatically rendered by WebCore.

[GTK] Cleanup ScrollbarThemeGtk
https://bugs.webkit.org/show_bug.cgi?id=152830

Reviewed by Michael Catanzaro.

Use a common path for GTK+ 3.19 and previous versions, simplifying
the code and removing a lot of ifdefs. Use always a new
GtkStyleContext, but when painting cache the newly created one so
all paint methods use that one. We were also caching some theme
properties assuming they don't change unless the theme changes,
but some of them can have different values depending on the state,
for example, when hovered or pressed. Those properties are now
only cached when we create a new GtkStyleContext.
The method updateScrollbarsFrameThickness() has also been removed,
since the Scrollbar constructor already initializes the frame rect
using the scrollbarThickness(). This method was not doing anything
anyway, since that was called on the constructor of the theme,
when there were no scrollbars registered. This also means we no
longer need to track registered/unregistered scrollbars.

Implement a sampling profiler
https://bugs.webkit.org/show_bug.cgi?id=151713

Reviewed by Filip Pizlo.

Source/JavaScriptCore:

This patch implements a sampling profiler for JavaScriptCore
that will be used in the Inspector UI. The implementation works as follows:
We queue the sampling profiler to run a task on a background
thread every 1ms. When the queued task executes, the sampling profiler
will pause the JSC execution thread and attempt to take a stack trace.
The sampling profiler does everything it can to be very careful
while taking this stack trace. Because it's reading arbitrary memory,
the sampling profiler must validate every pointer it reads from.

The sampling profiler tries to get an ExecutableBase for every call frame
it reads. It first tries to read the CodeBlock slot. It does this because
it can be 100% certain that a pointer is a CodeBlock while it's taking a
stack trace. But, not every call frame will have a CodeBlock. So we must read
the call frame's callee. For these stack traces where we read the callee, we
must verify the callee pointer, and the pointer traversal to an ExecutableBase,
on the main JSC execution thread, and not on the thread taking the stack
trace. We do this verification either before we run the marking phase in
GC, or when somebody asks the SamplingProfiler to materialize its data.

The SamplingProfiler must also be careful to not grab any locks while the JSC execution
thread is paused (this means it can't do anything that mallocs) because
that could cause a deadlock. Therefore, the sampling profiler grabs
locks for all data structures it consults before it pauses the JSC
execution thread.

[SVG -> OTF Converter] Parsing failures cause use of incomplete fonts
https://bugs.webkit.org/show_bug.cgi?id=152772
<rdar://problem/24043104>

Reviewed by Simon Fraser.

Source/WebCore:

Originally, if we fail to parse a glyph, we would simply skip the glyph. However, this means that
we will create an incomplete font without all the necessary glyphs. This causes very distressing
text where all the occurances of a particular letter are missing. Instead, we should treat the

[JSC] Iterating over a Set/Map is too slow
https://bugs.webkit.org/show_bug.cgi?id=152691

Reviewed by Saam Barati.

Source/JavaScriptCore:

Set#forEach and Set & for-of are very slow. There are 2 reasons.

forEach is implemented in C++. And typically, taking JS callback and calling it from C++.

C++ to JS transition seems costly. perf result in Linux machine shows this.

Samples: 23K of event 'cycles', Event count (approx.): 21446074385
34.04% jsc libjavascriptcoregtk-4.0.so.18.3.1 . JSC::Interpreter::execute(JSC::CallFrameClosure&)
20.48% jsc libjavascriptcoregtk-4.0.so.18.3.1 . vmEntryToJavaScript

7.95% jsc libjavascriptcoregtk-4.0.so.18.3.1 . JSC::setProtoFuncForEach(JSC::ExecState*)
5.65% jsc perf-22854.map . 0x00007f5d2c204a6f

Writing forEach in JS eliminates this.

Samples: 23K of event 'cycles', Event count (approx.): 21255691651
62.91% jsc perf-22890.map . 0x00007fd117c0a3b9

0.15% jsc libjavascriptcoregtk-4.0.so.18.3.1 . JSC::Lexer<unsigned char>::lex(JSC::JSToken*, unsigned int, bool)

Iterator result object allocation is costly.

Iterator result object allocation is costly. Even if the (1) is solved, when executing Set & for-of, perf result shows very slow performance due to (2).

Samples: 108K of event 'cycles', Event count (approx.): 95529273748
18.02% jsc libjavascriptcoregtk-4.0.so.18.3.1 . JSC::createIteratorResultObject(JSC::ExecState*, JSC::JSValue, bool)
15.68% jsc jsc . JSC::JSObject::putDirect(JSC::VM&, JSC::PropertyName, JSC::JSValue, unsigned int)
14.18% jsc libjavascriptcoregtk-4.0.so.18.3.1 . JSC::PrototypeMap::emptyObjectStructureForPrototype(JSC::JSObject*, unsigned int)
13.40% jsc perf-25420.map . 0x00007fce158006a1

6.79% jsc libjavascriptcoregtk-4.0.so.18.3.1 . JSC::StructureTransitionTable::get(WTF::UniquedStringImpl*, unsigned int) const

In the long term, we should implement SetIterator#next in JS and make the iterator result object allocation written in JS to encourage object allocation elimination in FTL.
But seeing the perf result, we can find the easy to fix bottleneck in the current implementation.
Every time createIteratorResultObject creates the empty object and use putDirect to store properties.
The pre-baked Structure* with done and value properties makes this implementation fast.

After these improvements, the micro benchmark[1] shows the following.

old:

Linked List x 212,776 ops/sec ±0.21% (162 runs sampled)
Array x 376,156 ops/sec ±0.20% (162 runs sampled)
Array forEach x 17,345 ops/sec ±0.99% (137 runs sampled)
Array for-of x 16,518 ops/sec ±0.58% (160 runs sampled)
Set forEach x 13,263 ops/sec ±0.20% (162 runs sampled)
Set for-of x 4,732 ops/sec ±0.34% (123 runs sampled)

new:

Linked List x 210,833 ops/sec ±0.28% (161 runs sampled)
Array x 371,347 ops/sec ±0.36% (162 runs sampled)
Array forEach x 17,460 ops/sec ±0.84% (136 runs sampled)
Array for-of x 16,188 ops/sec ±1.27% (158 runs sampled)
Set forEach x 23,684 ops/sec ±2.46% (139 runs sampled)
Set for-of x 12,176 ops/sec ±0.54% (157 runs sampled)

Set#forEach becomes comparable to Array#forEach. And Set#forEach and Set & for-of are improved (1.79x, and 2.57x).
After this optimizations, they are still much slower than linked list and array.
This should be optimized in the long term.

It should be possible to run liveness over registers without also tracking Tmps
https://bugs.webkit.org/show_bug.cgi?id=152963

Reviewed by Saam Barati.

Source/JavaScriptCore:

This adds a RegLivenessAdapter so that we can run Liveness over registers. This makes it
easier to write certain kinds of phases, like ReportUsedRegisters. I anticipate writing more
code like that for handling cold function calls. It also makes code like that somewhat more
scalable, since we're no longer using HashSets.

Currently, the way we track sets of registers is with a BitVector. Normally, we use the
RegisterSet class, which wraps BitVector, so that we can add()/contains() on Reg's. But in
the liveness analysis, everything gets turned into an index. So, we want to use BitVector
directly. To do that, I needed to make the BitVector API look a bit more like a set API. I
think that this is good, because the lack of set methods (add/remove/contains) has caused
bugs in the past. This makes BitVector have methods both for set operations on bits and array
operations on bits. I think that's good, since BitVector gets used in both contexts.

Source/WTF:

Add set methods (add/contains/remove) to BitVector, since it gets used as a set in a lot of
places. This also makes BitVector a drop-in replacement for HashSet<unsigned> in a lot of
places.

Also made the iterator methods of BitVector live on BitVector directly rather than behind the
thing returned from setBits(). This makes sense since that makes BitVector even more of a
drop-in for HashSet. It's not harmful since we've never added any other mode of iterating a
BitVector other than this, so it doesn't make sense to make it harder to access.

ARM64 does not have a "S" version of MUL setting the flags.

The FTL allocated spill slots for BinaryOps is sometimes inaccurate.
https://bugs.webkit.org/show_bug.cgi?id=152918

Reviewed by Filip Pizlo and Saam Barati.

ftl/FTLCompile.cpp:
Updated a comment.
ftl/FTLLowerDFGToLLVM.cpp:

(JSC::FTL::DFG::LowerDFGToLLVM::lower):

The code to compute maxNumberOfCatchSpills was unnecessarily allocating an extra slot for BinaryOps that don't have Untyped operands, and failing to allocate that extra slot for some binary ops. This is now fixed.

tests/stress/ftl-shr-exception.js:
tests/stress/ftl-xor-exception.js:
Un-skipped these tests. They now pass with this patch.

Absolute positioning -webkit-search-cancel-button crashes Safari.
https://bugs.webkit.org/show_bug.cgi?id=152847
<rdar://problem/24112087>

Reviewed by Simon Fraser.

Do not call offsetFromContainer while resolving the painting position for the search/cancel button renderer.
It skips the static positioned parent input renderer, when the search/cancel renderer is absolute positioned.
This patch also fixes a rendering glitch when the margin-right is > 0.

https://bugs.webkit.org/show_bug.cgi?id=152940

Reviewed by Zalan Bujtas.

Call into the display list recorder for top-level entrypoints implemented in platform-specific
files.

The convention is that if a function begins with "platform", it's not a top-level
entry point, and should only be called when there's a platform context (i.e. not
recording, and not paintingDisabled).

A few instances are stubbed out until we have a more complete display list implementation.

I was trying to get tail-call-varargs-no-stack-overflow.js.ftl-no-cjit-validate to work and
at first I hit the stack overflow issue and then I hit the varargs tail call issue. That's
why I have two fixes in one change. Now the test passes.

B3 needs Neg()
https://bugs.webkit.org/show_bug.cgi?id=152925

Reviewed by Mark Lam.

Previously we said that negation should be represented as Sub(0, x). That's wrong, since
for floats, Sub(0, 0) == 0 while Neg(0) == -0.

One way to solve this would be to say that anyone trying to say Neg(x) where x is a float
should instead say BitXor(x, -0). That's actually correct, but I think that it would be odd
to use bitops to represent floating point operations. Whatever cuteness this would have
bought us would be outweighed by the annoyance of having to write code that matches
Sub(0, x) for integer negation and BitXor(x, -0) for double negation. For example, this
would mean strictly more code for anyone implementing a Neg(Neg(x))=>x strength reduction.
Also, I suspect that the omission of Neg would cause others to make the mistake of using
Sub to represent floating point negation.

So, this introduces a proper Neg() opcode to B3. It's now the canonical way of saying
negation for both ints and floats. For ints, we canonicalize Sub(0, x) to Neg(x). For
floats, we lower it to BitXor(x, -0) on x86.

This reduces the number of failures from 13 to 12.

Consider painting to be disabled on a GraphicsContext with no platform data, and make updatingControlTints() immutable state
https://bugs.webkit.org/show_bug.cgi?id=152927

Reviewed by Tim Horton.

GraphicsContext had setters for paintingDisabled and updatingControlTints, but neither
were changed dynamically.

We can eliminate paintingDisabled by simply considering a GraphicsContext that was
created with no platform context to be paint-disabled.

We make updatingControlTints immutable state by providing a constructor that takes
a "NonPaintingReasons" enum, and doesn't create platform data.

More functions in platform code were protected by if (paintingDisabled())...

FTL B3 compile() doesn't clear exception handlers before we add FTL-specific ones
https://bugs.webkit.org/show_bug.cgi?id=152922

Reviewed by Saam Barati.

FTL B3 was generating a handler table that first contained the old baseline handlers keyed
by baseline's bytecode indices and then the FTL handlers keyed by FTL callsite index. That's
wrong, since the FTL code block should not contain any baseline handlers. The fix is to
clear the handlers before generation, sort of like FTL LLVM does.

Also added some stuff to make it easier to inspect the handler table.

This reduces the numbe rof failures from 25 to 13.

Reviewed by Andreas Kling.

Without this,

Optional<int> o = flag ? 1 : Nullopt;

would cause Nullopt to be treated as an integer, causing o to be initialized to 0,
instead of Nullopt. With this change, the above code now causes a compile error.

Also, get rid of the CONSTEXPR macro since all compilers support constexpr properly,
and add a WTF::makeOptional to match the current iteration of std::experimental::optional.

GraphicsContext::computeLineBoundsAndAntialiasingModeForText() always integral ceils the origin y position to offset underline text.
This additional visual overflow offset is not taken into account by visualOverflowForDecorations().
Unfortunately we can't compute the exact same offset value while collecting repaint rects, because
computeLineBoundsAndAntialiasingModeForText() uses CTM scaling before adjusting the offset position.

This code was crashing in some tests that forced GC slow paths because it was stubbed out
due to the use of undef. B3 doesn't have undef. In this case, there's no good reason to use
undef. We can just use zero. Since the path is dead anyway in that case, we weren't gaining
any LLVM optimizations by using undef.

Perf dashboard should automatically add aggregators
https://bugs.webkit.org/show_bug.cgi?id=152818

Reviewed by Chris Dumez.

When an aggregator entry is missing in aggregators table, automatically insert it in /api/report.

In a very early version of the perf dashboard, we had the ability to define a custom aggregator
in an admin page. In practice, nobody used or needed this feature so we got rid of it even before
the dashboard was landed into WebKit repository. This patch cleans up that mess.

run-tests.js:

(main): Added the filtering capability.
(TestEnvironment): Expose the config JSON in the test environment.

public/include/report-processor.php:

(ReportProcessor): Renamed name_to_aggregator now that it only contains ID.
(ReportProcessor::construct): No longer fetches the aggregator table. An equivalent work is done
in newly added ensure_aggregators.
(ReportProcessor::process): Calls ensure_aggregators which populates name_to_aggregator_id.
(ReportProcessor::ensure_aggregators): Added. Add the builtin aggregators: Arithmetic, Geometric,
Harmonic, and Total.
(TestRunsGenerator): Renamed name_to_aggregator now that it only contains ID.
(TestRunsGenerator::construct):
(TestRunsGenerator::add_aggregated_metric): Don't include aggregator_definition here since it's
never used now that all the aggregations are done natively in PHP.
(TestRunsGenerator::$aggregators): Added. We don't include SquareSum since it's only used for
computing run_square_sum_cache in test_runs table and it's useless elsewhere.
(TestRunsGenerator::aggregate_values): Add a comment about that.

tests/api-report.js: Updated a test case to reflect the change.

Web Inspector: Make creating new rules in the Styles sidebar simpler

FTL B3 getById() should do exceptions
https://bugs.webkit.org/show_bug.cgi?id=152810

Reviewed by Saam Barati.

This adds abstractions for doing exceptions from patchpoints, and uses them to implement
exceptions from GetById. This covers all of the following ways that a GetById might throw an
exceptions:

Throw without try/catch from the vmCall() in a GetById(Untyped:)
Throw with try/catch from the vmCall() in a GetById(Untyped:)
Throw without try/catch from the callOperation() in the patchpoint of a GetById
Throw with try/catch from the callOperation() in the patchpoint of a GetById
Throw without try/catch from the Call IC generated in the patchpoint of a GetById
Throw with try/catch from the Call IC generated in the patchpoint of a GetById

This requires having a default exception target in FTL-generated code, and ensuring that this
target is generated regardless of whether we have branches to the B3 basic block of the
default exception target. This also requires adding some extra arguments to a
PatchpointValue, and then knowing that the arguments are used for OSR exit and not anything
else. This also requires associating the CallSiteIndex of the patchpoint with the register
set used for exit and with the OSR exit label for the unwind exit.

All of the stuff that you have to worry about when wiring a patchpoint to exception handling
is covered by the new PatchpointExceptionHandle object. You create one by calling
preparePatchpointForExceptions(). This sets up the B3 IR representation of the patchpoint
with stackmap arguments for the exceptional exit, and creates a PatchpointExceptionHandle
object that can be used to create zero or more actual OSR exits. It can create both OSR exits
for operation calls and OSR exits for unwind. You call the
PatchpointExceptionHandle::scheduleExitCreationXXX() methods from the generator callback to
actually get OSR exits.

This API makes heavy use of Box<>, late paths, and link tasks. For example, you can use the
PatchpointExceptionHandle to get a Box<JumpList> that you can append exception jumps to. When
you use this API, it automatically registers a link task that will link the JumpList to the
actual OSR exit label.

This API is very flexible about how you get to the label of the OSR exit. You are encouraged
to use the Box<JumpList> approach, but if you really just need the label, you can also get
a RefPtr<ExceptionTarget> and rely on the fact that the ExceptionTarget object will be able
to vend you the OSR exit label at link-time.

This reduces the number of JSC test failures with FTL B3 from 186 to 133. It also adds a
bunch of new tests specifically for all of the ways you might throw from GetById, and B3
passes all of these new tests. Note that I'm not counting the new tests as part of the
previous 186 test failures (FTL B3 failed all of the new tests prior to this change).

After this change, it should be easy to make all of the other patchpoints also handle
exceptions by just following the preparePatchpointForExceptions() idiom.

ARM64 has two kinds of addressing with immediates:
-Signed 9bits direct (really only -256 to 255).
-Unsigned 12bits scaled by the load/store size.

When resolving the stack addresses, we easily run
past -256 bytes from FP. Addressing from SP gives us more
room to address the stack efficiently because we can
use unsigned immediates.

Directly-composited animated GIFs never resume once scrolled offscreen
https://bugs.webkit.org/show_bug.cgi?id=152817
<rdar://problem/19982020>

Reviewed by Daniel Bates.

Source/WebCore:

Directly-composited animated GIFs would never resume once scrolled
offscreen. This is because calling repaint() in this case would not
cause BitmapImage::draw() to be called and the animation would thus
not be resumed. To address the problem,
repaintForPausedImageAnimationsIfNeeded() now calls
RenderBoxModelObject::contentChanged(ImageChanged) in addition to
repaint() to make sure the animation actually gets resumed, even in
the directly-composited animated GIF case.

purpose of testing.

to cover this bug as our rendering code believed it has resumed the
animations but the GIF was not actually animating due to it being
directly-composited.

[JSC] Re-enable lea() in Air on ARM64
https://bugs.webkit.org/show_bug.cgi?id=152832

Patch by Benjamin Poulain <bpoulain@apple.com> on 2016-01-07
Reviewed by Michael Saboff.

Lea() on the MacroAssembler is not the full x86 Lea (the real one being
x86Lea32()). Instead, it is a addPtr() with SP and a constant.

The instruction is required to implement B3's StackSlot. It is not
safe for big offsets but none of the stack operations are at the moment.

Reduce max simultaneous connections from 35 to 17, because (a) all major browsers except
Chrome use 17, and (b) Chrome uses 10. The only reason we previously used 35 was that other

Factor free standing tree style resolve functions into a class
https://bugs.webkit.org/show_bug.cgi?id=152786

Reviewed by Simon Fraser.

Factor the free standing tree style resolve functions into a class that can keep state.
Style::TreeResolver instances resolve a single tree scope. It is instantiated for resolving
the document style and then recursively for each encountered shadow tree.

This will enable new features and optimizations later.

dom/Document.cpp:

(WebCore::Document::recalcStyle):

Move the root style computation code back to Document. It fits better here and avoid some
awkwardness with style resolver construction order.

style/StyleResolveTree.cpp:

(WebCore::Style::TreeResolver::TreeResolver):

TreeResolver knows the current tree context and the StyleResolver to use for it.
Switch the functions to use these instead of recomputing them repeatedly.

(WebCore::Style::shouldCreateRenderer):
(WebCore::Style::TreeResolver::styleForElement):
(WebCore::Style::moveToFlowThreadIfNeeded):

(WebCore::Style::TreeResolver::createRenderTreeForBeforeOrAfterPseudoElement):
