Aart Bik fe6daed58b [vm/compiler] "fast"-path for x64 division 
Rationale:
Since 64-bit division requires twice as many cycles
and has much higher latency compared to the 32-bit
division, even for a non-speculative 64-bit path,
a 32-bit "fast path" makes sense.

Speedup:
About 2x for cases that fit 32-bits. No noticable
slowdown for the 64-bit cases.
