Reviewed by Geoff Garen.

JIT::resetPatchPutById calls the the wrong thing on x86-64 – this is moot right now,
since they currently both do the same thing, but if we were to ever make compact mean
8-bit this could be a real problem. Also, relying on the object still being in eax
on entry to the transition stub isn't very robust - added nonArgGPR1 to at least make
this explicit.

* jit/JITPropertyAccess.cpp:
(JSC::JIT::emitSlow_op_put_by_id):
    - copy regT0 to nonArgGPR1
(JSC::JIT::privateCompilePutByIdTransition):
    - DataLabelCompact -> DataLabel32
(JSC::JIT::resetPatchPutById):
    - reload regT0 from nonArgGPR1
* jit/JSInterfaceJIT.h:
(JSInterfaceJIT):
    - added nonArgGPR1
