2192a315a4 Second step in allocating objects in generated code on ARM. 
Objects which require an additional fixed array to be allocated now have this allocated in generated code as well. Added allocation flags to the macro assembler new space allocation routines.

Changed the ia32 and x64 macro assemblers to take allocation flags to the allocation routines instead of boolean flag.

717394492d Generate specialized constructor code for constructing simple objects. 
For objects which only have simple assignments of the form this.x = ...; a
specialized constructor stub is now generated. This generated code allocates the
object and fills in the initial properties directly. If this fails for some
reason code continues in the generic constructor stub which in turn might pass
control to the runtime system.

Added counter to see how many objects are constructed using a specialized stub.

The specialized stub is only implemented for ia32 architecture in this change.
For x64 and ARM the generic construct stub is used.

This is change is identical to http://codereview.chromium.org/174392 (committed in r2753 and reverted in r2754) except that a few parts have already been committed from http://codereview.chromium.org/173469 (committed in r2762).

9edc69c72f Add support for (some) assignment expressions to the CFG builder and 
fast-mode compiler.

1. We avoid generating a useless temporary for assignments with
nontrivial right-hand sides.  Instead of translating id = expr into:

...
tmp = <last expr instruction>
id = tmp

we generate directly

...
id = <last expr instruction>

by passing a data destination ('hint') down the AST.  The semantics is
to use the destination as a result location if a temp is needed.  It
may be ignored.  NULL indicates I don't care and you should generate a
temp.

2. We correctly handle assignments as subexpressions.  When building
the CFG for an expression we accumulate the assigned variables and we
emit a move to a fresh temporary if a value in a variable is in
jeopardy of being overwritten.

1ce28eda0b - Expose CanvasPixelArray functionality directly in JavaScript 
indexed property accesses.
- The IC stubs have not been updated to handle these directly, but
  at least we do not have to leave the VM to access bytes.

1ca19c383d Fix ARM compiler crash in short-circuited boolean expressions. 
We did not handle the case where the left-hand-side expression was
fully compiled to control flow.  There were also some assertions for
unary and binary expressions that crashed debug builds when the
expression was fully compiled to control flow.

Regression test added.

76833936b7 Make Array::kHeaderSize protected, and only use kHeaderSize of its subclasses. 
Many X64 bugs have been due to the difference between (unaligned) Array::kHeaderSize and (aligned) FixedArray::kHeaderSize.
