cmd/compile: be sure to wrap defer/go calls with arguments

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.
