Reuse the index from promoted nodes when coloring executed tasks
https://github.com/rust-lang/rust/pull/138824 did not correctly handle the case where a dep node was promoted green, but later or concurrently executed. It resulted in multiple dep nodes being allocated to it. This fixes that by checking that the node was not previously green in the encoder lock.
This also fixes a race when forcing diagnostic nodes introduced in https://github.com/rust-lang/rust/pull/138824.
https://github.com/rust-lang/rust/pull/138824 should get reverted on beta.
This should fix#139110.

Ensure `swap_nonoverlapping` is really always untyped
This replaces #134954, which was arguably overcomplicated.
## Fixes#134713
Actually using the type passed to `ptr::swap_nonoverlapping` for anything other than its size + align turns out to not work, so this goes back to always erasing the types down to just bytes.
(Except in `const`, which keeps doing the same thing as before to preserve `@RalfJung's` fix from #134689)
## Fixes#134946
I'd previously moved the swapping to use auto-vectorization *on bytes*, but someone pointed out on Discord that the tail loop handling from that left a whole bunch of byte-by-byte swapping around. This goes back to manual tail handling to avoid that, then still triggers auto-vectorization on pointer-width values. (So you'll see `<4 x i64>` on `x86-64-v3` for example.)
Remove unnecessary `mut` in test.
The value is moved in `pin!()`, so the binding doesn't need to be `mut` itself.
(Rustc doesn't warn about this due to the current hacky implementation of `pin!()`. That is fixed by https://github.com/rust-lang/rust/pull/139114.)
compiletest: don't use stringly paths for `compose_and_run`
Eventually I'd like to fully migrate to `camino`'s `{Utf8Path,Utf8PathBuf}` because compiletest assumes UTF-8 paths all over the place, so this is an precursor change to make the migration diff cleaner.

Rename some `name` variables as `ident`.
It bugs me when variables of type `Ident` are called `name`. It leads to silly things like `name.name`. `Ident` variables should be called `ident`, and `name` should be used for variables of type `Symbol`.
This commit improves things by by doing `s/name/ident/` on a bunch of `Ident` variables. Not all of them, but a decent chunk.

fix "still mutable" ice while metrics are enabled
Resolves "still mutable" ICE discovered by `@matthiaskrgr` here: [#t-docs-rs > metrics intitiative @ 💬](https://rust-lang.zulipchat.com/#narrow/channel/356853-t-docs-rs/topic/metrics.20intitiative/near/510490790)
This was caused by invoking `crate_hash` before the `definitions` struct was frozen here: e643f59f6d/compiler/rustc_interface/src/passes.rs (L951)
resolved by moving metrics dumping to occur after `analysis` freezes the definitions
I'm guessing we didn't discover this in CI because the problem only occurs when you try to calculate the crash hash with incremental compilation enabled when it tries to freeze the definitions here: e643f59f6d/compiler/rustc_middle/src/hir/map.rs (L1172)
my understanding is that this causes us to freeze the definitions too early in compilation, then we subsequently try to mutate them, likely during `analysis`, and this causes the ICE.

Tracking issue template: fine-grained information on style update status
Inspired by some of the communication issues around the stabilization of
`let`-chains, give more fine-grained information about the status of
updating style for any new syntax.
This does not change the process or blockers in any way; it only
*documents* the current state in the tracking issue. For instance, in
the case of `let`-chains, we would have checked the boxes for "Style
team decision" and "(non-blocking) Formatting has been implemented", and
not checked the box for the style guide. That would have then provided
better supporting information for any decisions.
