Remove clubby789 from review rotation
These days I'm unfortunately too busy to be able to take up reviews, and it looks like some PRs have been blocked on this 😓
Added dots at the sentence ends of rustc AST doc
Just a tiny improvement for the AST documentation by bringing consistency to sentence ends. I intentionally didn't terminate every sentence, there are still some members not having them, but at least there's no mixing style on the type level.
Use `ControlFlow` results for visitors that are only looking for a single value
These visitors all had a `Option<Value>` or `bool` field, that, once set, was never unset or modified again. They have been refactored by removing the field and returning `ControlFlow` directly from the visitor
Improve readability of some fmt code examples
Some indent was weird. Some examples were too long (overall better to keep it to maximum 80 columns, but only changed the most outstanding ones).

Split `SolverDelegate` back out from `InferCtxtLike`
This is because in order to uplift things like the `Generalizer` and other `TypeRelation`s, we want to be able to interface with `InferCtxtLike` (and `InferCtxt` as its implementation), rather that `SolverDelegate`, which only really exists as a hack to be able to define some downstream methods in `rustc_type_ir`.

Improve well known value check-cfg diagnostic for the standard library
This PR adjust the current logic for hidding the rustc/Cargo suggestion to add a value to a well-known name to exclude the standard library and rustc crates.
This is done in order to improve the contributor experience, in particular when adding a new target, which often requires adding some cfgs like `target_os` which may not be available yet in stage0.

The diagnostic code would look like this.

= help: consider using a Cargo feature instead
= help: or consider adding in `Cargo.toml` the `check-cfg` lint config for the lint:
[lints.rust]
unexpected_cfgs = { level = "warn", check-cfg = ['cfg(target_os, values("blable"))'] }
= help: or consider adding `println!("cargo::rustc-check-cfg=cfg(target_os, values(\"blable\"))");` to the top of the `build.rs`
= note: see <https://doc.rust-lang.org/nightly/rustc/check-cfg/cargo-specifics.html> for more information about checking conditional configuration
= note: `-D unexpected-cfgs` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(unexpected_cfgs)]`
```

Improve dead code analysis
Fixes#120770
1. check impl items later if self ty is private although the trait method is public, cause we must use the ty firstly if it's private
2. mark the adt live if it appears in pattern, like generic argument, this implies the use of the adt
3. based on the above, we can handle the case that private adts impl Default, so that we don't need adding rustc_trivial_field_reads on Default, and the logic in should_ignore_item

Make CI more agnostic of the owning GitHub organization
This should make it possible to switch running `auto` and `try` builds from `rust-lang-ci` to `rust-lang`.

coverage: Rename `mir::coverage::BranchInfo` to `CoverageInfoHi`
This opens the door to collecting and storing coverage information that is unrelated to branch coverage or MC/DC, during MIR building.
There is no change to the output of coverage instrumentation, but one deliberate change is that functions now *always* have an attached `CoverageInfoHi` (if coverage is enabled and they are eligible), even if they didn't collect any interesting branch information.

Update windows-bindgen to 0.58.0
This also switches from the bespoke `std` generated bindings to the normal `sys` ones everyone else uses.
This has almost no difference except that the `sys` bindings use the `windows_targets::links!` macro for FFI imports, which we implement manually. This does cause the diff to look much larger than it really is but the bulk of the changes are mostly contained to the generated code.
Migrate `include_bytes_deps`, `optimization-remarks-dir-pgo`, `optimization-remarks-dir`, `issue-40535` and `rmeta-preferred` `run-make` tests to rmake

DependencyList: removed outdated comment
Comment was outdated. Didn't updated description, as `Linkage` enum have descriptive names.
Also added fixme about moving this file to rustc_metadata.

Miri function identity hack: account for possible inlining
Having a non-lifetime generic is not the only reason a function can be duplicated. Another possibility is that the function may be eligible for cross-crate inlining. So also take into account the inlining attribute in this Miri hack for function pointer identity.
That said, `cross_crate_inlinable` will still sometimes return true even for `inline(never)` functions:
- when they are `DefKind::Ctor(..) | DefKind::Closure` -- I assume those cannot be `InlineAttr::Never` anyway?
- when `cross_crate_inline_threshold == InliningThreshold::Always`
so maybe this is still not quite the right criterion to use for function pointer identity.
cache type sizes in type-size limit visitor
This is basically https://github.com/rust-lang/rust/pull/125507#issuecomment-2206813779 as lcnr can't open the PR now.
Locally it reduces the `itertools` regression by quite a bit, to "only +50%" compared to nightly (that includes overhead from the local lack of artifact post-processing, and is just a data point to compare to the 10-20x timings without the cache).

Remove a use of `StructuredDiag`, which is incompatible with automatic error tainting and error translations
fixes#127219
I want to remove all of `StructuredDiag`, but it's a bit more involved as it is also used from the `ItemCtxt`, which doesn't support tainting yet.
