2f2243c9b6 Auto merge of #99843 - oli-obk:is_useful_perf, r=compiler-errors
Some `is_useful` cleanups

#98582 was reverted because it was a perf regression.

https://github.com/rust-lang/rust/pull/99806 reintroduces the changes, but this PR picks individual ones that have no regressions.

Rollup merge of #99911 - cjgillot:no-guess, r=davidtwco
Remove some uses of `guess_head_span`

That function cuts a span at the first occurrence of `{`.  Using `def_span` is almost always more precise.

Rollup merge of #99518 - dingxiangfei2009:let-else-additional-tests, r=oli-obk
Let-else: break out scopes when a let-else pattern fails to match

This PR will commit to a new behavior so that values from initializer expressions are dropped earlier when a let-else pattern fails to match.

Fix #98672.
Close #93951.

Rollup merge of #99651 - compiler-errors:fn-and-raw-ptr-in-const-generics, r=oli-obk
Deeply deny fn and raw ptrs in const generics

I think this is right -- just because we wrap a fn ptr in a wrapper type does not mean we should allow it in a const parameter.

We now reject both of these in the same way:

```
#![feature(adt_const_params)]

#[derive(Eq, PartialEq)]
struct Wrapper();

fn foo<const W: Wrapper>() {}

fn foo2<const F: fn()>() {}
```

This does regress one test (`src/test/ui/consts/refs_check_const_eq-issue-88384.stderr`), but I'm not sure it should've passed in the first place.

Implement `for<>` lifetime binder for closures

This PR implements RFC 3216 ([TI](https://github.com/rust-lang/rust/issues/97362)) and allows code like the following:

```rust
let _f = for<'a, 'b> |a: &'a A, b: &'b B| -> &'b C { b.c(a) };
//       ^^^^^^^^^^^--- new!

Rollup merge of #99140 - TaKO8Ki:implement-is-accessible-span, r=fee1-dead
Implement `SourceMap::is_span_accessible`

This patch adds `SourceMap::is_span_accessible` and replaces `span_to_snippet(span).is_ok()` and `span_to_snippet(span).is_err()` with it. This removes a `&str` to `String` conversion.
