c102c5cfc6 Auto merge of #96020 - martingms:optimize-relate_substs, r=nnethercote 
Micro-optimize `ty::relate::relate_substs` by avoiding `match`

Was a top-20 hot function in a callgrind profile of compiling `bitmaps-3.1.0`.

Yields some small speedups on that crate and some others according to local benching:

29c78cc086 Add {open,close}_delim arguments to TokenCursorFrame::new(). 
This will facilitate the change in the next commit.

`boolean` arguments aren't great, but the function is only used in three

02317542eb Rearrange TokenCursor::inlined_next(). 
In particular, avoid wrapping a token within `TokenTree::Token` and then
immediately matching it and returning the token within. Just return the
token immediately.

b1e6dee596 Merge TokenCursor::{next,next_desugared}. 
And likewise for the inlined variants.

I did this for simplicity, but interesting it was a performance win as
well.

ad566b78f2 Tweak Cursor::next_with_spacing. 
This makes it more like `CursorRef::next_with_spacing`. There is no
performance effect, just a consistency improvement.

e2661bac6d Auto merge of #95379 - icewind1991:suggest-associated-type-more, r=jackh726 
show suggestion to replace generic bounds with associated types in more cases

Moves the hint to replace generic parameters with associated type bounds from the "not all associated type bounds are specified"(`E0191`) to "to many generic type parameters provided"(`E0107`).

Since `E0191` is only emitted in places where all associated types must be specified (when creating `dyn` types), the suggesting is currently not shown for other generic type uses (such as in generic type bounds). With this change the suggesting is always emitted when the number of excess generic parameters matches the number of unbound associated types.

Main motivation for the change was a lack of useful suggesting when doing

```rust
fn foo<I: Iterator<usize>>(i: I) {}
```

1ec2c136b3 Auto merge of #95779 - cjgillot:ast-lifetimes-undeclared, r=petrochenkov 
Report undeclared lifetimes during late resolution.

First step in https://github.com/rust-lang/rust/pull/91557

We reuse the rib design of the current resolution framework. Specific `LifetimeRib` and `LifetimeRibKind` types are introduced. The most important variant is `LifetimeRibKind::Generics`, which happens each time we encounter something which may introduce generic lifetime parameters. It can be an item or a `for<...>` binder. The `LifetimeBinderKind` specifies how this rib behaves with respect to in-band lifetimes.

Refactor HIR item-like traversal (part 1)

Issue  #95004

- Create hir_crate_items query which traverses tcx.hir_crate(()).owners to return a hir::ModuleItems
- use tcx.hir_crate_items in tcx.hir().items() to return an iterator of hir::ItemId
- use tcx.hir_crate_items to introduce a tcx.hir().par_items(impl Fn(hir::ItemId)) to traverse all items in parallel;
