Add allocation support to ia32 macro assembler

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.
