CL 298669 implemented wrapping for defer/go calls so the function being called with defer or go statement has no arguments. This simplifies the compiler and the runtime, especially with the new ABI. If the called function does not have any argument, we don't need to wrap. But the code missed the cases of method receiver, as well as some apparent argumentless builtin calls which may later be rewritten to having arguments (e.g. recover). This CL makes sure to wrap those cases. Also add a check to ensure that go and defer calls are indeed argumentless. Handle "defer recover()" specially, as recover() is lowered to runtime.gorecover(FP) where FP is the frame's FP. FP needs to be evaluated before wrapping. Updates #40724.
