Ok then. Unless reviewers think it would be best to have separate diag groups for "builtin" and "user-provided" binary operators,
i'll just extend the `-Wself-assign` / `-Wself-assign-field` / `-Wself-move` (i wonder, does it work both the fields and usual variables, or not).

(That means, stage2 self-hosting testing will be needed...)
