bcf5912b3f 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.

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

1a3c3cee9d 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.
