Documentation has been updated in https://github.com/rust-lang/reference/pull/1055. cc #86860 for previous stabilization report.

Not yet marks https://github.com/rust-lang/rust/issues/60553 as done: need documentation in the rust reference.

43dd3d514b Auto merge of #103284 - compiler-errors:const-sad, r=oli-obk 
Revert "Unify tcx.constness and param env constness checks"

Too much of a perf regression https://github.com/rust-lang/rust/pull/102975#issuecomment-1282702513, and an attempt in #103263 didn't fix it except for just a tiny bit.

This change isn't really needed (see https://github.com/rust-lang/rust/pull/102830#issuecomment-1272514096), so this should be an easy revert.

d159124dbd Rollup merge of #103536 - Enselic:remove-set_sigpipe_handler, r=tmiasko 
Remove `rustc_driver::set_sigpipe_handler()`

Its usage was removed in https://github.com/rust-lang/rust/pull/102587 and https://github.com/rust-lang/rust/pull/103495, so we do not need to keep it around any longer. According to [preliminary input](https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp/topic/Find.20.60rustc_driver.60.20dependent.20projects.3F/near/304490764), we do not need to worry about any deprecation cycle for this explicitly unstable API, and can just straight up remove it.

f2c2e582bd Rollup merge of #103209 - Xiretza:multiple-suggestions, r=davidtwco 
Diagnostic derives: allow specifying multiple alternative suggestions

This allows porting `span_suggestions()` to diagnostic structs.

Doesn't work for `multipart_suggestions()` because the rank would be reversed - the struct would specify multiple spans, each of which has multiple possible replacements, while `multipart_suggestions()` creates multiple possible replacements, each with multiple spans.

suggest type annotation for local statement initialed by ref expression

In a local statement with a type declaration, if a ref expression is used on the right side and not used on the left side, in addition to removing the `&` and `&mut` on the right side, we can add them on the left side alternatively

d49e7e7fa1 Auto merge of #103279 - compiler-errors:normalize-hack-back, r=lcnr 
Add eval hack in `super_relate_consts` back

Partially reverts 01adb7e98d.

This extra eval call *still* needs to happen, for example, in `normalize_param_env_or_error` when a param-env predicate has an unnormalized constant, since the param-env candidates never get normalized during candidate assembly (everywhere else we can assume that they are normalized fully).

r? `@lcnr,` though I feel like I've assigned quite a few PRs to you in the last few days, so feel free to reassign to someone else familiar with this code if you're busy!

cc #103243 (fixes the issue, but don't want to auto-close that until a backport is performed).

Assert if inference vars are leaking from `InferCtxt::fully_resolve`

`InferCtxt::fully_resolve` shouldn't return unresolved inference vars without us at least being aware of it, so make it an assertion now. This should only happen in cases where we used to be returning `ReEmpty`...

bed4ad65bf Auto merge of #102340 - JakobDegen:pass-manager-simplification, r=oli-obk 
Split phase change from `MirPass`

The main goal here is to simplify the pass manager logic. `MirPass` no longer contains the `phase_change` method, and `run_passes` instead accepts an `Option<PhaseChange>`. The hope is that this addresses the comments (and maybe perf regression) from #99102 .

8b494f427c Allow impl Fn() -> impl Trait in return position 
This allows writing the following function signatures:
```rust
fn f0() -> impl Fn() -> impl Trait;
fn f3() -> &'static dyn Fn() -> impl Trait;
```

These signatures were already allowed for common traits and associated
types, there is no reason why `Fn*` traits should be special in this
regard.
