The tests sometimes fail on bots as they don't have time to collect enough samples. This change makes them use counter of samples taken when v8 is either in JS or EXTERNAL state and repeat sampling until desired threshold is reached.

Bugfix: The general array constructor stub did not handle the case
...
properly when it is called with a function pointer in the type cell,
instead assuming that an AllocationSite object should be present. The
case where this can happen is if the cell is uninitialized, then the
first constructor call made is to the Array function of a different
context. In that case, we'll store the function pointer in the cell,
and then go ahead and call the array constructor stub too. The bug is
fixed by checking for the AllocationSite object map. If not found, the
constructor stub goes forward with a default ElementsKind, just as in
several other cases.
A test in allocation-site-info.js was beefed up to make sure the state
chain described above is traversed.

Add internal fields to JSArrayBufferViews (JSTypedArray and JSDataView)

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.

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.

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.

CpuProfiler: eliminate 2 layers of 4 for CodeCreateEvent calls.
...
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.

Hydrogen array constructor cleanup and improvements

* 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.

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.

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.

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

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.

Make sure CallIC is in monomorphic state when starting profiling in NativeAccessorNameInProfile2
...
Changed cctest/test-cpu-profiler/NativeAccessorNameInProfile2 to make a few warm-up cycles before starting profiler so that accessor invocations performed via monomorphic inline caches and slow paths traces do not distort the profile.
Drive-by: removed logging code that was used to diagnose NativeAccessorNameInProfile2 failures on Windows.
