Cuong Manh Le c82304b712 cmd/compile: do not devirtualize defer/go calls ...

For defer/go calls, the function/method value are evaluated immediately.
So after devirtualizing, it may trigger a panic when implicitly deref
a nil pointer receiver, causing the program behaves unexpectedly.

It's safer to not devirtualizing defer/go calls at all.

Fixes #52072
