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

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.

b90bd6987b 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.

a9a80fb422 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).

106a477443 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.

was called as a function. Issue was found with optimize_constructed_array
turned on. This patch makes the fix, and turns the flag back on.

710c245a41 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.

09c489ea93 Re-land: Implement ObservedArrayPop, ObservedArrayShift, ObservedArrayUnshift & ObservedArraySplice 
Original issue: https://codereview.chromium.org/15331002/

Broke mozilla/js1_5/Array/regress-451483.js, which ends up attempting to call %IsObserved() on a non-object.

IsObserved now checks for JSReceiver and returns false rather than crashing.
