Use HashStable_Generic in rustc_type_ir
A lot of the types in this crate implemented HashStable directly to avoid circular dependencies. One way around that is to use HashStable_Generic. We adopt that here to avoid a lot of boilerplate.
This doesn't update all the types, because some would require `I: Interner + HashStable`.

Avoid UB in the Windows filesystem code in... bootstrap?
This basically a subset of the changes from https://github.com/rust-lang/rust/pull/101171. I didn't think to look in src/bootstrap for more windows filesystem API usage, which was apparently a mistake on my part. It's kinda goofy that stuff like this is in here, but what are you gonna do, computers are awful.
I also added `winbase` to the `winapi` dep -- I tested this in a tmp crate but needed to add this to your Cargo.toml -- you `use winapi::stuff::winbase` in this function, but are relying on something else turning on that feature.
Rollup merge of #101399 - cjgillot:borrowck-binding-span, r=estebank
Shrink span for bindings with subpatterns.
Bindings with nested patterns (`binding @ pat` syntax) currently point to the full pattern. This PR proposes to shrink the span to stop before the ````@`.``` This makes the diagnostics for move/mutability conflicts clearer, as they not point to the `binding` only, instead of the full pat.
Auto merge of #101504 - lqd:rust-lld-fix, r=petrochenkov
Fix `-Zgcc-ld=lld`
`-Zgcc-ld=lld` is currently broken. CI is currently ignoring its tests.
cc `@Mark-Simulacrum` on the `compiletest` change: I'm not sure which of `bootstrap`'s test step or `compiletest` is currently incorrect wrt windows' `--compile-lib-path`. Since `sysroot/bin` is passed on windows, that means that `compiletest` can't find `rust-lld` on windows and tests are currently ignored: it's looking for something that is in `sysroot/lib` instead.
They are currently ignored on unixes for a different reason: the lld wrapper has a different name than what is checked.
(I've changed `compiletest` in this PR, just because I could make a very targeted change there, whereas completely changing the intentional lib path that is passed seemed it'd have wider reaching implications on all tests.)
And in both unix/win cases, I've changed the detection to look for `rust-lld` rather than the wrappers in `bin/gcc-ld/`. It seems like the more stable of all these executable names.
r? `@petrochenkov`
I've tested the `lld-wrapper` change on linux and osx, but couldn't test on windows gnu targets (I only have MSVC targets, and these can't use `rust-lld` via `-Zgcc-ld=lld`, nor do they use the lld wrapper IIUC).
I'd expect it to work whether or not the wrapper is called with or without an executable suffix. But at least now CI should test it in these targets.

This doesn't update all the types, because some would require
`I: Interner + HashStable`.
Fixes https://github.com/rust-lang/rust-clippy/issues/9307 and makes the `arithmetic` lint behave like `integer_arithmetic`.
It is worth noting that literal integers of a binary operation (`1 + 1`, `i32::MAX + 1`), **regardless if they are in a constant environment**, won't trigger the lint. Assign operations also have similar reasoning.

Based on the call stack, where [`class='methods'`] calls `trait_item` and [`trait_item`] calls [`document`], this div selector was probably intended to target docblock and stability tags.
In the current version of the code, neither of these can possibly be nested directly below the `class='methods'` wrapper, because the [current version of the `trait_item` function] always wraps them in a `<details>` tag if they exist. The only div tag that can possibly be nested directly below it now is the one with class `method`, which is explicitly excluded.

rustdoc: remove unused mobile CSS `.rustdoc { flex-direction }`
According to MDN, [flex-direction] only applies to [flex containers], which are boxes with `display: flex` or `inline-flex`.
However, the `.rustdoc` body container is not a flex-container on mobile. A few lines above, it's set to `display: block`, so this selector does not have any effect.
You can see when this one used to be triggered by visiting <https://doc.rust-lang.org/1.54.0/alloc/slice/index.html#structs-1> in a very narrow window, but it doesn't any more, because the module table is now rendered using `<div>` tags.

Rollup merge of #101435 - JakobDegen:bitwidth-tests, r=wesleywiser
Remove unnecessary `EMIT_MIR_FOR_EACH_BITWIDTH`
This commit removes the annotation only for those tests where the 32 bit and 64 bit files were exactly identical. I didn't touch anything in the `mir-opt/const` directory, since having this annotation there seems more principled, even if it doesn't make a difference.
This also removes four additional files related to the `separate_const_switch.rs` test. The associated annotations were removed in #100827 , but I forgot to remove the files as well. (#97564 is the issue tracking an automated check here)

Add -api-level to pm command
As of ~Aug 30th, `pm build` commands require an `api-level` flag. This flag should match the fuchsia api-level that's being targeted by the code. Since this is dependent on the version of the SDK that's being used, we may want to change this to something a bit more robust in the future.

now that CI correctly detects rust-lld in run-make tests, we ignore this
test since it relies on `-Zgcc-ld=lld` which is not made to work on the
windows-msvc targets: it requires a gcc flavor.

Track PGO profiles in depinfo
This PR makes sure that PGO profiles (`-Cprofile-use` and `-Cprofile-sample-use`) are tracked in depinfo, so that when they change, the compilation session will be invalidated.
This approach was discussed on [Zulip](https://rust-lang.zulipchat.com/#narrow/stream/246057-t-cargo/topic/Tracking.20PGO.20profile.20files.20in.20cargo).
I tried it locally and it seems that the code is recompiled just with this change, and https://github.com/rust-lang/rust/pull/100413 is not even needed. But it's possible that not everything required is recompiled, so we will probably want to land both changes.
Another approach to implement this could be to store the PGO profiles in `sess.parse_sess.file_depinfo` when the session is being created, but then the paths would have to be converted to a string and then to a symbol, which seemed unnecessarily complicated.

Make `HandleCycleError` an enum instead of a macro-generated closure
- Add a `HandleCycleError` enum to rustc_query_system, along with a `handle_cycle_error` function
- Move `Value` to rustc_query_system, so `handle_cycle_error` can use it
- Move the `Value` impls from rustc_query_impl to rustc_middle. This is necessary due to orphan rules.

rustdoc: remove outdated CSS `.sub-variant > div > .item-info`
This CSS still matches sometimes, as you can see in <https://doc.rust-lang.org/1.63.0/std/collections/enum.TryReserveErrorKind.html#variant.AllocError.fields>, but since nothing else is setting `margin-top`, putting it back to `initial` does nothing.
This selector was added here, but it was called `.stability` instead of `.item-info` at the time, probably as an override for the selector immediately above it that sets a negative margin:

Compile spin_loop_hint as pause on x86 even without sse2 enabled
The x86 `pause` instruction was introduced with sse2, but because it is encoded as `rep nop`, it works just fine on cpu's without sse2 support. It just doesn't do anything.
