[JSC] Improve op_mod for int32 uses and add LOL support

rdar://170243169
Reviewed by Marcus Plutowski.
Right now Baseline just goes to the slow path for ARM64 on op_mod. This
patch adds a fast path for binary int32s (assuming the divisor is
non-zero). Also, clean-up some of the DFG's equivalent code.
