Fix for ​https://bugs.webkit.org/show_bug.cgi?id=22837
Remove dependency on the bytecode Instruction buffer in Interpreter::cti_op_call_NotJSFunction
Part of <rdar://problem/6428342>

• interpreter/CallFrame.h: Added comment regarding returnPC storing a void*.
• interpreter/Interpreter.cpp: (JSC::bytecodeOffsetForPC): We no longer have any cases of the PC being in the instruction stream for JIT, so we can remove the check. (JSC::Interpreter::cti_op_call_NotJSFunction): Use the CTI_RETURN_ADDRESS as the call frame returnPC as it is only necessary for looking up when throwing an exception.
• interpreter/RegisterFile.h: (JSC::RegisterFile::): Added comment regarding returnPC storing a void*.
• jit/JIT.h: Remove ARG_instr4.
• jit/JITCall.cpp: (JSC::JIT::compileOpCallSetupArgs): Don't pass the instruction pointer.
