345cc98a25 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.

7e0ee5301e 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.

9ef762b683 Do not store fp and sp values in TickSample
Their values are not used neither by the tick processor nor by CpuProfiler so it is just a waste of space.

TickSample used to be a transport for grabbed register values to TickSample::Trace, now they are passed in a special structure RegisterState which is allocated on the stack for the sampling period.

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

44dfaa2a1e Fix test-cpu-profiler/FunctionCallSample flakiness under GC stress testing
The test flakes on "V8 GC Stress" bots and the sample looks like this:
[Top down]:
   90     0   (root) [-1] #0 1
    1     1    (program) [-1] #0 2
   89    89    (garbage collector) [-1] #0 3
which means that almost all samples are inside GC and we have no |start| node in the collected profile.

Running the test with different combinations of --gc-interval=500 and --stress-compaction flags gives the results quoted below. They don't give a ground to require |start| node presense in the profile when doing GC stress testing. So this change makes the |start| node optional in the collected profile if GC stress testing is on.

559e1d4540 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).

4c5508b42f 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.

0ac0edb707 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.

* Cleanup of LCallNewArray::PrintDataTo() method

* 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.

4aeccdb23e 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.

2ab2e4843e Introduce THREADED_PROFILED_TEST macro
A bunch of tests in test-api.cc need to be executed two times: with CPU profiler on and off to check different code paths. There are only two such tests at the moment but I'm going to add more and having this logic duplicated in all these tests look awkward. The tests are executed as part of Threading* tests and there is no much sense in running CPU profiler in that case. This change addresses both problems by introducing THREADED_PROFILED_TEST macro which mosly resembles THREADED_TEST except that when such test is executed as a standalone test (not part of a test-api/Threading*) it will first run the test normally and the start CPU profiler and run the test again.

If an array literal contains some non-constant elements, is of type SMI, and
then the boilerplate transitions to double or fast sometime after we've

c4224f09a2 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

93ab1864ea Allow the deoptimizer translation to track de-materialized objects.
This allows the deoptimizer to materialize objects (e.g. the arguments
object) while deopting without having a consective stack area holding
the object values. The LEnvironment explicitly tracks locations for
these values and preserves them in the translation.

cc27c4c41b GeneratorFunction() makes generator instances
The current specification has GeneratorFunction() be like Function(),
except that it makes generator instances.  This commit implements that
behavior.  It also fills in a piece of the implementation where
otherwise calling GeneratorFunction or GeneratorFunctionPrototype would
cause an abort because they have no code.

418ddc800a Allocate generator result objects before unwinding try handlers
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.
