This replaces the '[volatile]' flag. Now, class_method and super_method are only used for vtable dispatch. The witness_method instruction is still overloaded for use with both ObjC protocol requirements and Swift protocol requirements; the next step is to make it only mean the latter, also using objc_method for ObjC protocol calls.
