I don't think we need this. I don't expect optimized code to somehow
deoptimize and end up here. (At least I think that's what this is for).

src/ia32/full-codegen-ia32.cc:204: __ cmp(ecx,
Immediate(Smi::FromInt(0)));
No need for this cmp. dec also sets the flags. Just do a j(not_zero,
&loop_header) later. (not_zero is actually the same flag as not_equal).
