2023-09-27Auto merge of #116163 - compiler-errors:lazyness, r=oli-obkbors-12/+5
Don't store lazyness in `DefKind::TyAlias` 1. Don't store lazyness of a type alias in its `DefKind`, but instead via a query. 2. This allows us to treat type aliases as lazy if `#[feature(lazy_type_alias)]` *OR* if the alias contains a TAIT, rather than having checks for both in separate parts of the codebase. r? `@oli-obk` cc `@fmease`

2023-09-20Auto merge of #115486 - compiler-errors:dont-capture-late-pls, r=cjgillotbors-3/+1
Correctly deny late-bound lifetimes from parent in anon consts and TAITs Reuse the `AnonConstBoundary` scope (introduced in #108553, renamed in this PR to `LateBoundary`) to deny late-bound vars of *all* kinds (ty/const/lifetime) in anon consts and TAITs. Side-note, but I would like to consolidate this with the error reporting for RPITs (E0657): https://github.com/rust-lang/rust/blob/c4f25777a08cd64b710e8a9a6159e67cbb35e6f5/compiler/rustc_hir_analysis/src/collect/resolve_bound_vars.rs#L733-L754 but the semantics about what we're allowed to capture there are slightly different, so I'm leaving that untouched. Fixes #115474

Make it clearer that we're just checking for an RPITIT Tiny nit to use `is_impl_trait_in_trait` more, to make it clearer that we're just checking whether a def-id is an RPITIT, rather than doing something meaningful with the `opt_rpitit_info`. r? `@spastorino`

Make `Bound::predicates` use `Clause` Part of #107250 `Bound::predicates` returns an iterator over `Binder<_, Clause>` instead of `Predicate`. I tried updating `explicit_predicates_of` as well, but it seems that it needs a lot more change than I thought. Will do it in a separate PR instead.
