sgjesse@chromium.org a4eed24c26 Add allocation support to ia32 macro assembler.
Factored out the allocation in new space from assembler code into the macro assembler. To support the current allocation patterns a number of different functions where required.

This is change is identical to http://codereview.chromium.org/174524 (committed in r2768 and reverted in r2769) except that line 710 in macro-assembler-ia32.cc is

  cmp(result_end, Operand::StaticVariable(new_space_allocation_limit));

instead of

  cmp(result, Operand::StaticVariable(new_space_allocation_limit));

and pre-submit fixes as well.
