Use impl substs in `#[rustc_on_unimplemented]` We were using the trait-ref substs instead of impl substs in `rustc_on_unimplemented`, even when computing the `rustc_on_unimplemented` attached to an impl block. Let's not do that. This PR also untangles impl and trait def-ids in the logic in `on_unimplemented` a bit. Fixes #94675 |
