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.

2a56e33da7 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.

1d4c64591b MIPS: Fix abs_d instruction in the simulator. 
The abs_d instruction was implemented wrongly in the simulator,
it doesn't reverse the sign of the -0 number.

This commit fixes the abs_d instruction implementation.

88021e64b1 MIPS: Use compare nil ic only for non-strict equality.

Original commit message:
Strict-equality only has one check and cannot deopt. Should therefore not be part of the stub.

eb7e2771a9 MIPS: Generator object "next" method takes optional send value. 
Port r15028 (258a047)

Original commit message:
Update the generators implementation to make "next" also do the job of
what was previously called "send" by taking an optional argument.
Remove send, and do a bunch of renamings.

2ebb95071a MIPS: Fix LoadIC calling convention. 
Port r15027 (3ffb343)

Original commit message:
The comments in ic-arm.cc::LoadIC indicated that the receiver should be
both in a register and on the stack. This isn't true in fact: the code
is careful to spill the receiver if needed.

This CL also fixes up a mistaken use of this convention in VisitYield.
