As a sanity check, [this tool] can be used to run a CSS query across an HTML
tree to detect if a selector ever matches (I use compiler-docs and std
docs). This isn't good enough, because I also need to account for JavaScript,
but this class is never mentioned in any of the JS files, either.
According to [blame], this class was added when rustdoc was first written,
and, as far as I can tell, was never actually used.

Update stdarch submodule
Changes from stdarch:
* Fix links in documentation of cmpxchg16b
* Use load intrinsic and loop for intrinsic-test programs. Add --release flag back to intrinsic-test programs.
* Properly fix vext intrinsic tests
* Replace some calls to `pointer::offset` with `add` and `sub`
* Allow internal use of stdsimd from detect_feature
* fix target name in contributing.md
* Tweak constant for ARM vext instruction tests
* Use `llvm.ppc.altivec.lvx` intrinsic for `vec_ld`
* Adding doc links for arm neon intrinsics
* Adding doc links for arm crypto and aes intrinsics
* Remove instruction tests for `__mmask*` intrinsics
* Update ubuntu 21.10 docker containers to 22.04
* Adding documentation links for arm crc32 intrinsics
* Remove restrictions on compare-exchange memory ordering.
* Fix a typo in the document.
* Allow mapping a runtime feature to a set of target_features
* Update atomic intrinsics
* Fully qualify recursive macro calls
* Ensure the neon vector aggregates like `float32x4x4_t` are `#[repr(C)]`
* Remove useless conditional compilation
* Fix ARM vbsl* NEON intrinsics

so that it is the only pass responsible for elaboration, instead of
splitting this responsibility between the `StateTransform` and
`ElaborateBoxDerefs`.
Check projection types before inlining MIR
Fixes https://github.com/rust-lang/rust/issues/100550
I'm very unhappy with this solution, having to duplicate MIR validation code, but at least it removes the ICE.
r? `@compiler-errors`
A resume place is evaluated and assigned to only after a yield
terminator resumes. Ensure that locals used when evaluating the
resume place are live across the yield.
Elide superfluous storage markers
Follow the existing strategy of omitting the storage markers for temporaries
introduced for internal usage when elaborating derefs and deref projections.
Those temporaries are simple scalars which are used immediately after being
defined and never have their address taken. There is no benefit from storage
markers from either liveness analysis or code generation perspective.
Sync rustc_codegen_cranelift
The main highlights this time are support for parallel compilation of codegen units (by me) and improved windows support (by ``@afonso360)`` In addition ``@afonso360`` added abi-checker to cg_clif's CI. This has already catched an abi compatibility issue with AArch64. The fix has landed on Cranelift's main branch, but doesn't yet have a release. ``@uweigand`` also submitted a couple of PR's that will are prerequisites for supporting IBM's s390x architecture.

rustdoc: ayu code color selector more specific
According to https://github.com/rust-lang/rust/pull/100960#issuecomment-1225970579, this selector is only really intended to apply to item info. However, it's so broad that it's hard to tell when it deliberately applies vs where it accidentally applies.
let-else: break out to one scope higher for let-else
```@est31``` This PR follows up with #99518 which is to break out to the last remainder scope. It breaks to the out-most `region_scope` of the block if the first statement is a `let-else`.
