Generate StoreGlobal stubs with Hydrogen
...
- Constants globals are inlined into Hydrogen code using code dependencies that invalidate the Crankshafted code when global PropertyCells or the global object change.
- The more general case generates code that is just as good as the hand-written assembly stubs on all platforms.

Add internal fields to JSArrayBufferViews (JSTypedArray and JSDataView)
...
In Blink, JSTypedArray and JSDataView objects act as "wrappers" for C++
objects. Wrapping protocol in Blink requires all wrapper JavaScript objects
to have a certain amount of internal fields that Blink uses for
book-keeping (essentially a pointer to C++ object and some type
information). This change adds those internal fields to JSTypedArray and
JSDataView, in a similiar way to how it is done for JSArrayBuffer.

Some common pieces were moved from platform-dependent code into Sampler::SampleStack and TickSample::Init.

Correctly report stack trace when current function is FunctionApply builtin

When pc is inside FunctionApply builtin function the top frame may be either
2) Internal stack frame created by FunctionApply itself.
In this case we know its caller's pc and can correctly resolve calling function.
1) Frame of the calling JavaScript function that invoked .apply(). In this case we have no practical reliable way to find out the caller's pc so we mark the caller's frame as 'unresolved'.
All this logic is implemented in ProfileGenerator. SafeStackFrameIterator is extended to provide type of the current top stack frame (iteration actually starts from the caller's frame as we know top function from pc).

Correctly report callstack when current function is FunctionCall builtin
...
When current function is FunctionCall builtin we have no reliable way to determine its caller function (in many cases the top of the sampled stack contains address of the caller but sometimes it does not). Instead of dropping the sample or its two top frames we simply mark the caller frame as '(unresolved function)'. It seems like a better approach that dropping whole sample as knowing the top function and the rest of the stack the user should be able to figure out what the caller was.
This change adds builtin id to CodeEntry objects. It will be used later to add similar top frame analysis for FunctionApply and probably other builtins.

Test that profiler is stopped when isolate is being disposed
...
The only way to get v8::CpuProfiler instance in the V8 public API is to call v8::Iolate::GetCpuProfiler(). The method will return NULL if the isolate has not been initialized yet or has been torn down already. It is the client's reponsibility to make sure that CPU profiling has been stopped before disposing of the isolate.
This CL adds a test for this and several ASSRTS enforcing that assumptions. This allowed to be sure that heap is always setup when CPU profiling is being started. Based on that the number of places where already compiled functions are reported to the profiler event processor boils down to the single place (CpuProfiler::StartProcessorIfNotStarted). I'm going to rely on this assumption in further changes.

The bodies of methods in ProfilerEventProcessor were moved into CpuProfiler.
Multiple NewCodeEntry methods in CpuProfilesCollection were replaced with one which
simply passes arguments to the CodeEntry constructor.
And CpuProfiler just calls this method when it needs a CodeEntry object.
This NewCodeEntry method is required because CpuProfilesCollection keeps ownership of CodeEntry objects.

And CpuProfiler just calls this method when it needs a CodeEntry object.
This NewCodeEntry method is required because CpuProfilesCollection keeps ownership of CodeEntry objects.

Fix infinite loop in regress-opt-after-deopt.
...
%CompleteOptimization attempts to install optimized functions
that the parallel thread has put on the output queue, as long as
the function is marked with a builtin. However, activating the
debugger will set all functions to the lazy recompile builtin,
without the function being on the parallel recompilation pipeline.
So we wait for the function to finish parallel recompilation
while it's marked by a builtin that's unrelated to parallel
recompilation.

MIPS: Hydrogen array constructor cleanup and improvements.
...
Port r15383 (3e90aaf)
Original commit message:
* Cleanup of LCallNewArray::PrintDataTo() method
* Created HCallNewArray::PrintDataTo()
* Created many more tests in array-constructor-feedback.js
* Removed redundant instructions in
GenerateRecordCallTarget
* Bugfix in CreateArrayDispatchOneArgument: on a call to
new Array(0), we'd like to set the type feedback cell to
a packed elements kind, but we shouldn't do it if the
cell contains the megamorphic sentinel.
* When used from crankshaft, ArrayConstructorStubs can
avoid verifying that the function being called is the
array function from the current native context, relying
instead on the fact that crankshaft issues an
HCheckFunction to protect the constructor call. (this
new minor key is used in LCodeGen::DoCallNewArray(), and
influences code generation in
CodeStubGraphBuilderBase::BuildArrayConstructor()).
* Optimization: the array constructor specialized for
FAST_SMI_ELEMENTS can save some instructions by looking
up the correct map on the passed in constructor, rather
than indexing into the array of cached maps per element
kind.

This change introduces StackFrameIteratorBase which owns singleton frame instances and encapsulates some basic iterator functionality. It has two actual implementations: StackFrameIterator and SafeStackFrameIterator.
All logic specific to frame iteration at a random point (basically checks that fp and sp extracted from stack frames are within current stack boundaries) used only by CPU profiler is now concentrated in SafeStackFrameIterator.
Generic stack iteration used in all other places is put into StackFrameIterator. Also this iterator unlike SafeStackFrameIterator iterates through stack handlers.
StackAddressValidator and ExitFrameValidator classes were removed in favor of inline checks and simple methods.

Do not iterate stack handlers in SafeStackFrameIterator
...
CPU profiler doesn't use stack handlers so there is no need to iterate through them while traversing stack. This change SafeStackFrameIterator always iterate only frames and removes checks corresponding to the handlers iteration.
The problem described in the bug occurred because of a false assumption in SafeStackFrameIterator that if Isolate::c_entry_fp is not NULL then the top frame on the stack is always a C++ frame. It is false because we may have entered JS code again, in which case JS_ENTRY code stub generated by JSEntryStub::GenerateBody() will save current c_entry_fp value but not reset it to NULL and after that it will create ENTRY stack frame and JS_ENTRY handler on the stack and put the latter into Isolate::handler(top). This means that if we start iterating from c_entry_fp frame and try to compare the frame's sp with Isolate::handler()->address() it will turn out that frame->sp() > handler->address() and the condition in SafeStackFrameIterator::CanIterateHandles is not held.

Each StackFrame instance is owned by single iterator and has a pointer to it so we can simply mark the iterator as "safe" or not and read the field in the stack frames instead of going into the isolate.

Simplify stack iterators implementation
...
In order to fix https://code.google.com/p/chromium/issues/detail?id=252097 I
need to change SafeStackTraceFrameIterator. Stack iterators hierarchy looks
excessively complicated and I'd like to flatten it a bit by removing some
intermediate classes. In particular there are two hierarchies sharing
JavaScriptFrameIteratorTemp<T> template for no good reason.
This change extracts some of JavaScriptFrameIteratorTemp functionality directly
into SafeStackTraceFrameIterator. This made it obvious that a few checks were
performed twice.
The rest of JavaScriptFrameIteratorTemp<T> is merged with
JavaScriptFrameIterator. Now that the class is not a template some of its
implementation is moved from frames-inl.h into frames.cc
So in this change I removed JavaScriptFrameIterator and
SafeJavaScriptFrameIterator. As the next step I'm going to merge
SafeStackFrameIterator into SafeStackTraceFrameIterator.

MIPS: Generators: Avoid calling into runtime if operand stack is empty

Port r15240 (909f716e)
Original commit message:
This patch makes yield sites save the resume continuation and context
inline. If the operand stack is empty, we can avoid a call into the
runtime. This also makes the SuspendJSGeneratorObject runtime function
less magical: it just has to save the operand stack and stack handlers.
This speeds up the following case by a factor of 3 or so:
function* until(n) {
for (var i = 0; i < n; i++)
yield i;
}
function sum(iter) {
var sum = 0;
for (var x of iter) sum += x;
return sum;
}
for (var i = 0; i < 10000; i++) sum(until(1000))
Also, there is no more sentinel value as the generators will resume in
the right place already, allowing me to remove the hack added to the
--debug-code check in r14437.

Reduce the amount of full code generated to fill out array literals.
...
This is achieved by tuning the calling convention of StoreArrayLiteralStub:
* The map of the array literal can be loaded in the stub from the
array literal itself, there is no need to pass it at all.
* The array literal is already on the stack, so there is no need to
pass it again via a register.
* The literal index is unchanged while filling the literal, so we can
push it on the stack once and avoid passing it every time. Note that
we need to mirror this change in the stack layout in crankshaft, too.

Notify CPU profiler when calling native getters
...
This change modifies code produced by BaseLoadStubCompiler::GenerateLoadCallback so that instead of calling AccessorGetter direcly it calls InvokeAccessorGetter which changes VM state and calls the actual callback. This way CPU profiler knows which external callback is being executed in this case. Indirect call happens only if CpuProfiler::is_profiling() is true.
This is exactly same change as r15116 with a build fix for test-api.cc

Notify CPU profiler when calling native getters
...
This change modifies code produced by BaseLoadStubCompiler::GenerateLoadCallback so that instead of calling AccessorGetter direcly it calls InvokeAccessorGetter which changes VM state and calls the actual callback. This way CPU profiler knows which external callback is being executed in this case.

MIPS: Allocate generator result objects before unwinding try handlers

Port r15079 (1ebdfdc6)
Original commit message:
When a generator suspends, it saves its state out to the heap and
unwinds try handlers but doesn't pop anything off the stack. Instead it
relies on no GC happening between the suspend and the return from the
generator. However this was not the case: boxing the result object
could cause GC, which would try to traverse the stack but would
misinterpret words from unwound try handlers as heap objects.
This CL changes to allocate the result objects before the suspend. It
also removes the generators-iteration skip introduced in r15065.

Improve code for integral modulus calculation.
...
Depending on what we know about the right operand, we basically do 3
different things (and the code is actually structured this way):
* If we statically know that the right operand is a power of 2, we do
some bit fiddling instead of doing a "real" modulus calculation.
This should actually be done on the Hydrogen level, not on the
Lithium level, but this will be a separate CL.
* If type feedback tells us that the right operand is a power of 2, we
do the same as above, but guarded by conditional deoptimization to
make sure that the assumption is still valid. In the long run, we
should make this guard visible on the Hydrogen level to make it
visible for GVN and other optimizations.
* In the general case we only do the minimum steps necessary and don't
try to be too clever, because cleverness actually slows us down on
real-world code.
If we look at the code gerators for LModI, we actually see that we
basically have 3 (4 on ARM) fundamentally different translations. I
don't really like lumping them together, they should probably be
different Lithium instructions. For the time being, I restructured the
generators to make this crystal-clear, at the cost of some duplication
regarding the power-of-2 cases. This will go away when we do the
strength reduction on the Hydrogen level, so I'd like to keep it as it
is for now.
Note that the MIPS part was only slightly restructured, there is still
some work to do there.

Allocation type info advice consumed in bailout path leads to assert failure.
...
If the runtime is taken for a constructor like "new Array(100000)", where
allocation site info already led to an elements kind of DOUBLE, then the runtime
would fail to transition the array to dictionary mode. Better to recognize this
case and avoid wasting time by following the advice. Furthermore, it offers a
way to recognize that the array should be in dictionary mode (though a future
checkin will capitalize on that).

MIPS: Turn off allocation site info for crankshafted array constructor calls.
...
Port r14934 (dbddd7e)
Original commit message:
Once we crankshaft a method, we should turn off allocation site info for
constructed arrays. Additionally, the semantics for doing this were
awkward because the constructed array code stubs get an
AllocationSiteMode as a minor key, but it's used as a permission to
determine the final mode locally based on ElementsKind. I refactored
this to a simpler boolean for override or local control.

Turn off allocation site info for crankshafted array constructor calls.
...
Once we crankshaft a method, we should turn off allocation site info for
constructed arrays. Additionally, the semantics for doing this were
awkward because the constructed array code stubs get an
AllocationSiteMode as a minor key, but it's used as a permission to
determine the final mode locally based on ElementsKind. I refactored
this to a simpler boolean for override or local control.

CPU profiler should support names of accessors set via v8::Object::SetAccessor
...
This change fixes the case when the accessors are invoked from JSObject::{Get,Set}PropertyWithCallback.
It already works for inlined calls generated by StoreStubCompiler::CompileStoreCallback. The same still needs to be fixed for getter invocations generated by BaseLoadStubCompiler::CompileLoadCallback, corresponding case is commented out in the new test.
This is a slightly modified version of r14915 which was rolled back due to test timeout on Windows. Compared to r14915 the new tests use OS::TimeCurrentMillis instead of OS::Ticks as OS::Ticks has ms precision on Windows and trying to wait 10 ticks (us) will result in at least 1 ms pause.

This removes the FACTORY helper macro to avoid accidental TLS access
when using the factory. Most internal code has access to the Isolate by
now whereas tests which are not performance critical still heavily use
TLS access through explicit Isolate::Current() calls.
