For .result = /abc.*/g we generate the following IA-32 code:

   ...
   mov ebx,[edi+0x17]
   mov eax,[ebx+0xb]
   cmp eax, 0xf5d0e135         ;; object: 0xf5d0e135 <undefined>
   jnz done
   push ebx
   push 0x2
   push 0xf5d13805             ;; object: 0xf5d13805 <String[5]: abc.*>
   push 0xf5d13815             ;; object: 0xf5d13815 <String[1]: g>
   call RuntimeStub_MaterializeRegExpLiteral
 done:
   push eax
   pop [ebp+0xf4]
   ...

This is very similar to the code previously generated except we do not 
generate deferred code for the case where we call the runtime.

On ARM we use the stm instruction to make pushing the arguments more compact.
