Rename and allow `cast_ref_to_mut` lint

This PR is a small subset of https://github.com/rust-lang/rust/pull/112431, that is the renaming of the lint (`cast_ref_to_mut` -> `invalid_reference_casting`).

BUT also temporarily change the default level of the lint from deny-by-default to allow-by-default until https://github.com/rust-lang/rust/pull/112431 is merged.

typeck in parallel

#108118 caused `typeck` to be transferred to the serial part (`check_unused`), which made the performance of parallel rustc significantly reduced.

This pr re-parallelize this part, which increases the average performance improvement of parallel rustc in `full` and `incr-full` scenarios from [14.4%](https://github.com/rust-lang/rust/pull/110284#issuecomment-1545354608) to [23.2%](https://github.com/rust-lang/rust/pull/110284#issuecomment-1624770626).

Rollup merge of #113005 - compiler-errors:dont-query-normalize, r=cjgillot
Don't call `query_normalize` when reporting similar impls

Firstly, It's sketchy to be using `query_normalize` at all during HIR typeck -- it's asking for an ICE 😅. Secondly, we're normalizing an impl trait ref that potentially has parameter types in `ty::ParamEnv::empty()`, which is kinda sketchy as well.

The only UI test change from removing this normalization is that we don't evaluate anonymous constants in impls, which end up giving us really ugly suggestions:

```
error[E0277]: the trait bound `[X; 35]: Default` is not satisfied
 --> /home/gh-compiler-errors/test.rs:4:5
  |
4 |     <[X; 35] as Default>::default();
  |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ the trait `Default` is not implemented for `[X; 35]`
  |
  = help: the following other types implement trait `Default`:
            &[T]
            &mut [T]
            [T; 32]
            [T; core::::array::{impl#30}::{constant#0}]
            [T; core::::array::{impl#31}::{constant#0}]
            [T; core::::array::{impl#32}::{constant#0}]
            [T; core::::array::{impl#33}::{constant#0}]
            [T; core::::array::{impl#34}::{constant#0}]
          and 27 others
```

So just fold the impls with a `BottomUpFolder` that calls `ty::Const::eval`. This doesn't work totally correctly with generic-const-exprs, but it's fine for stable code, and this is error reporting after all.

Rollup merge of #112506 - compiler-errors:const-infer-ice, r=b-naber
Properly check associated consts for infer placeholders

We only reported an error if it was in a "suggestable" position (according to `is_suggestable_infer_ty`) -- this isn't correct for infer tys that can show up in other places in the constant's type, like behind a dyn trait.

Adjust UI tests for `unit_bindings` lint

- Explicitly annotate `let x: () = expr;` where `x` has unit type, or remove the unit binding to leave only `expr;` instead.
- Use `let () = init;` or `let pat = ();` where appropriate.
- Fix disjoint-capture-in-same-closure test which wasn't actually testing a closure: `tests/ui/closures/2229_closure_analysis/run_pass/disjoint-capture-in-same-closure.rs`.

Note that unfortunately there's *a lot* of UI tests, there are a couple of places where I may have left something like `let (): ()` (this is not needed but is left over from an ealier version of the lint) which is bad style.

This PR is to help with the `unit_bindings` lint at #112380.

Rollup merge of #111991 - BoxyUwU:change_error_term_display, r=compiler-errors
Change ty and const error's pretty printing to be in braces

`[const error]` and `[type error]` are slightly confusing since they look like either a slice with an error type for the element ty or a slice with a const argument as the type ???. This PR changes them to display as `{const error}` and `{type error}`  similar to `{integer}`.

This does not update the `Debug` impls for them which is done in #111988.

I updated some error logic to avoid printing the substs of trait refs when unable to resolve an assoc item for them, this avoids emitting errors with `{type error}` in them. The substs are not relevant for these errors since we don't take into account the substs when resolving the assoc item.

Rollup merge of #111215 - BoxyUwU:resolve_anon_consts_differently, r=cjgillot
Various changes to name resolution of anon consts

Sorry this PR is kind of all over the place ^^'

Fixes #111012

- Rewrites anon const nameres to all go through `fn resolve_anon_const` explicitly instead of `visit_anon_const` to ensure that we do not accidentally resolve anon consts as if they are allowed to use generics when they aren't. Also means that we dont have bits of code for resolving anon consts that will get out of sync (i.e. legacy const generics and resolving path consts that were parsed as type arguments)
- Renames two of the `LifetimeRibKind`, `AnonConst -> ConcreteAnonConst` and `ConstGeneric -> ConstParamTy`
- Noticed while doing this that under `generic_const_exprs` all lifetimes currently get resolved to errors without any error being emitted which was causing a bunch of tests to pass without their bugs having been fixed, incidentally fixed that in this PR and marked those tests as `// known-bug:`. I'm fine to break those since `generic_const_exprs` is a very unstable incomplete feature and this PR _does_ make generic_const_exprs "less broken" as a whole, also I can't be assed to figure out what the underlying causes of all of them are. This PR reopens #77357 #83993
- Changed `generics_of` to stop providing generics and predicates to enum variant discriminant anon consts since those are not allowed to use generic parameters
- Updated the error for non 'static lifetime in const arguments and the error for non 'static lifetime in const param tys to use `derive(Diagnostic)`

I have a vague idea why const-arg-in-const-arg.rs, in-closure.rs and simple.rs have started failing which is unfortunate since these were deliberately made to work, I think lifetime resolution being broken just means this regressed at some point and nobody noticed because the tests were not testing anything :( I'm fine breaking these too for the same reason as the tests for #77357 #83993. I couldn't get `// known-bug` to work for these ICEs and just kept getting different stderr between CI and local `--bless` so I just removed them and will create an issue to track re-adding (and fixing) the bugs if this PR lands.

Rollup merge of #111100 - BoxyUwU:array_repeat_expr_wf, r=compiler-errors
check array type of repeat exprs is wf

Fixes #111091

Also makes sure that we actually renumber regions in the length of repeat exprs which we previously weren't doing and would cause ICEs in `adt_const_params` + `generic_const_exprs` from attempting to prove the wf goals when the length was an unevaluated constant with `'erased` in the `ty` field of `Const`

The duplicate errors are caused by the fact that `const_arg_to_const`/`array_len_to_const` in `FnCtxt` adds a `WellFormed` goal for the created `Const` which is also checked by the added `WellFormed(array_ty)`. I don't want to change this to just emit a `T: Sized` goal for the element type since that would ignore `ConstArgHasType` wf requirements and generally uncomfortable with the idea of trying to sync up `wf::obligations` for arrays and the code in hir typeck for repeat exprs.
