Keith Randall c26a32a500 cmd/compile,cmd/link: introduce generic interface call relocations
To capture the fact that a method was called on a generic interface,
so we can make sure the linker doesn't throw away any implementations
that might be the method called.

See the comment in reflect.go for details.

Fixes #49049
