fschneider@chromium.org 5820f951c1 Improve the allocation and initialization of locals on IA32 in the top-level compiler. 
This optimization is already done on x64 and ARM. 

Until now we used a push immediate for each local variable on IA32:

  push $undefined
  push $undefined
  ...

to initialize each local variable. This change does:

  mov eax, $undefined
  push eax
  push eax
  ...
