- Dropped separate `-Wself-assign-builtin` and `-Wself-assign-overloaded` groups
- Simply updated the existing `-Wself-assign` and `-Wself-assign-field`.
- Significantly improved test coverage.
- `ninja check-clang` passes. Did not do stage2 build yet.
- `-Wself-assign-field` is rather neglected - unlike `-Wself-assign`, it does incorrectly warn on self-operations with `volatile` stores, and macros.
