translation: doc comments with derives, subdiagnostic-less enum variants, more derive use
- Adds support for `doc` attributes in the diagnostic derives so that documentation comments don't result in the derive failing.
- Adds support for enum variants in the subdiagnostic derive to not actually correspond to an addition to a diagnostic.
- Made use of the derive in more places in the `rustc_ast_lowering`, `rustc_ast_passes`, `rustc_lint`, `rustc_session`, `rustc_infer` - taking advantage of recent additions like eager subdiagnostics, multispan suggestions, etc.
cc #100717
Elaborate supertrait bounds when triggering `unused_must_use` on `impl Trait`
Given `impl Trait`, if one of its supertraits has a `#[must_use]`, then trigger the lint. This means that, for example, `-> impl ExactSizeIterator` also triggers the `must_use` on `trait Iterator`, which fixes#102183.
This might need `@rust-lang/lang` sign-off, since it changes the behavior of the lint, so cc'ing them.
move hir typeck into separate crate
second part https://github.com/rust-lang/compiler-team/issues/529
I avoided pretty much anything that wasn't just a simple move + path adjustment. Left fixmes for methods which are at an odd place
r? `@compiler-errors`
Mark `std::os::wasi::io::AsFd` etc. as stable.
io_safety was stabilized in Rust 1.63, so mark the io_safety exports in `std::os::wasi::io` as stable.
Fixes#103306.

interpret: remove an incorrect assertion
This fixes an ICE in Miri, [reported](https://rust-lang.zulipchat.com/#narrow/stream/269128-miri/topic/SwitchInt.20with.20no.20targets.3F) by `@saethlin.` The faulty assertion was introduced by 432535da2b, when a previously correct assertion checking that the `otherwise` target exists got replaced by this assertion checking that at least one more target beyond `otherwise` exists.
Sadly we don't have a small reproducer so I don't think we can easily add a testcase.
Fixed docs typo in `library/std/src/time.rs`
* Changed comment from `Previous rust versions panicked when self was earlier than the current time.` to `Previous rust versions panicked when the current time was earlier than self.`
* Resolves#103282.
Adjust `transmute{,_copy}` to be clearer about which of `T` and `U` is input vs output
This is essentially a documentation-only change (although it does touch code in an irrelevant way).
linker: Fix weak lang item linking with combination windows-gnu + LLD + LTO
In https://github.com/rust-lang/rust/pull/100404 this logic was originally disabled for MSVC due to issues with LTO, but the same issues appear on windows-gnu with LLD because that LLD uses the same underlying logic as MSVC LLD, just with re-syntaxed command line options.
So this PR just disables it for LTO builds in general.
Fix the bug of next_point in source_map
There is a bug in `next_point`, the new span won't move to next position when be called in the first time.
For this reason, our current code is working like this:
1. When we really want to move to the next position, we called two times of `next_point`
2. Some code which use `next_point` actually done the same thing with `shrink_to_hi`
This fix make sure when `next_point` is called, span will move with the width at least 1, and also work correctly in the scenario of multiple bytes.

rustdoc: remove no-op CSS `nav.sub { font-size: 1rem }`
This rule originated as a `font-size: 16px`, when body had `font-size: 13px` set in 4fd061c426902b0904c65e64a3780b21f9ab3afb.
It remained even when body's font size was bumped up to 16px, 4d5f4ff5e9297dcad21612f9dd20ae4598b5b7e2, making the rule a no-op, and was carried forward when it was converted to 1rem in cc18120425a5c571a968d850c75cc935a8321136.

r? `@lcnr`
best reviewed one commit at a time, mostly because the second commit that fixes `ClosureOutlivesRequirement` is mostly noise because of losing its `<'tcx>` lifetime parameter.
Do anonymous lifetimes remapping correctly for nested rpits
Closes#103141
r? `@cjgillot` `@nikomatsakis`
This fixes a stable to stable regression that in my opinion is `P-critical` so, we probably want to backport it all the way up to stable.
