Fixes rust-lang#139082. Emits an error when `Self` is found in the projection bounds of a trait object. In type aliases, `Self` has no meaning, so `type A = &'static dyn B` where `trait B = Fn() -> Self` will expands to `type A = &'static Fn() -> Self` which is illegal, causing the region solver to bail out when hitting the uninferred Self. Bug: rust-lang#139082 Signed-off-by: xtex <[email protected]>
we already track this info in the `definitions` field
…er-errors compiler: report error when trait object type param reference self Fixes rust-lang#139082. Emits an error when `Self` is found in the projection bounds of a trait object.

…r-diag-hir-wf-check, r=oli-obk Don't construct preds w escaping bound vars in `diagnostic_hir_wf_check` See comment inline. Fixes rust-lang#139330 r? oli-obk
…l-with-proj, r=oli-obk Fix trait upcasting to dyn type with no principal when there are projections rust-lang#126660 (which I had originally authored, lol) had a subtle bug that is the moral equivalent of rust-lang#114036, which is that when upcasting from `dyn Principal<Projection = Ty> + AutoTrait` to `dyn AutoTrait`, we were dropping the trait ref for `Principal` but not its projections (if there were any). With debug assertions enabled, this triggers the assertion I luckily added in a2a0cfe, but even without debug assertions this is a logical bug since we had a dyn type with just a projection bound but no principal, so it caused a type mismatch. This does not need an FCP because this should've been covered by the FCP in rust-lang#126660, but we just weren't testing a case when casting from a `dyn` type with projections 😸 Fixes rust-lang#139418 r? ``@oli-obk`` (or anyone)
…stic, r=oli-obk Don't call `Span::with_parent` on the good path in `has_stashed_diagnostic` More unnecessary incurred span tracking avoided by not calling `span.with_parent(None)`. This is useless on its own but makes it much easier to fix other "span tracking on the good path" issues in the future. r? oli-obk
rm `RegionInferenceContext::var_infos` we already track this info in the `definitions` field r? types
… r=oli-obk Update some comment/docs related to "extern intrinsic" removal Follow-up to rust-lang#139455. r? ``@oli-obk``
