Description Michael Saboff 2013-10-17 11:04:44 PDT

This is no longer needed as the stack check and arity check are now operations.  
Change is to delete two instances of
    move(stackPointerRegister, GPRInfo::argumentGPR0);
    poke(GPRInfo::callFrameRegister, OBJECT_OFFSETOF(struct JITStackFrame, callFrame) / sizeof(void*));
in Source/JavaScriptCore/dfg/DFGJITCompiler.cpp
