d0437e781d MIPS: Simplify the deopt entry method. 
The t9 register will always hold the address of the current entry when deoptimizing,

299bf5652d Fix the heap profiler crash caused by memory layout changes between passes. 
The heap profiler randomly crashed because of memory corruption caused
by unexpected heap objects layout changes occured between count and fill
passes. The changes lead the number of retainers counted on the first pass
did not match its number on the fill pass leading to the out of bounds
array access.

Besides that the mark bit scheme has been changed to a plain vector one in
dominators building algorithm. It is up to 4x faster because of smaller
memory access footprint.

240e818f0c Fix inlining of strict mode constructors. 
Inlined strict mode functions (that are not called as methods) will get
their receiver reset to undefined. This should not happen when inlining
constructors.

This change also simplifies the test suite to reuse the same closures
into which constructors get inlined and use gc() to force V8 to forget
collected type feedback.

98b12bc085 Allocate new AccessorPairs with holes instead of undefined. 
This is essential for the upcoming map sharing with accessors, and we aleady
have enough machinery to handle the holes now. Furthermore, use "To" template in
2 nearby functions, and made naming a bit more consistent.

In a nutshell: This CL should have no visible effect at all at the moment.

5033b9b6d1 Re-land CL 9466047. 
Main change from the original CL: Call::ComputeTarget does not use IsProperty
anymore, because this would potentially need a holder, which we don't have
here. Using Map::LookupInDescriptors with a NULL holder is a bit fishy in
general, because one has to be *extremely* careful when using its LookupResult.

The original CL made Chrome's NetInternalsTest.netInternalsTourTabs browser test
fail, but it's a mystery how this could happen: We should never reach
Call::ComputeTarget via Call::RecordTypeFeedback with a CALLBACKS property,
because we never consider calls to them monomorphic, which is in turn because of
the stub cache leaving them in the pre-monomorphic state. Therefore, I don't
have a clue how to write a regression test for this...

As an additional tiny bonus, the --trace-opt output for deoptimizations has been
improved.

1e40f7ac2c Fix a register assignment bug in typed array stores without SSE3 available. 
The old code used a separate HToInt32 instruction which had a wrong register
constraint for the input register which caused wrong result when the stored value
is used after a typed array store. (UseRegister instead of UseTempRegister) when no
SSE3 is available.

This change fixes it by replacing HToInt32 with the corresponding HChange
instruction which has correct register contraints.

Port r10881 (0d25c61e).

Original commit message:

Generates inlined code for object allocation specific to the initial map
of the given constructor function. Also forces completion of inobject
slack tracking while crankshafting to finalize instance size of these
objects.
