Allow members of patch classes to be annotated with @patch. The VM ignores the annotation. I simply replaces the original method if the name matches, or reports an error if field names match. Adding a bit is_patched to members to do more checking remains a TODO. There are currently no unused bits available, and I don’t want to increase the size of Function objects for this.
