Don't release Miri if its tests only failed on Windows

Extends #66053 to Windows, so the released Miri won't be broken if its tests only fail on Windows.

Rollup merge of #82041 - notriddle:shared-from-slice-docs, r=m-ou-se
Add docs for shared_from_slice From impls

The advantage of making these docs is mostly in pointing out that these
functions all make new allocations and copy/clone/move the source into them.

These docs are on the function, and not the `impl` block, to avoid showing
the "[+] show undocumented items" button.

Rollup merge of #81506 - vo4:hwasan, r=nagisa
HWAddressSanitizer support

#  Motivation
Compared to regular ASan, HWASan has a [smaller overhead](https://source.android.com/devices/tech/debug/hwasan). The difference in practice is that HWASan'ed code is more usable, e.g. Android device compiled with HWASan can be used as a daily driver.

# Example
```
fn main() {
    let xs = vec![0, 1, 2, 3];
    let _y = unsafe { *xs.as_ptr().offset(4) };
}
```
```

# Comments/Caveats
* HWASan is only supported on arm64.
* I'm not sure if I should add a feature gate or piggyback on the existing one for sanitizers.
* HWASan requires `-C target-feature=+tagged-globals`. That flag should probably be set transparently to the user. Not sure how to go about that.

# TODO
* Need more tests.
* Update documentation.
* Fix symbolization.
* Integrate with CI

Allow casting mut array ref to mut ptr

Allow casting mut array ref to mut ptr

We now allow two new casts:

- mut array reference to mut ptr. Example:

      let mut x: [usize; 2] = [0, 0];
      let p = &mut x as *mut usize;

  We allow casting const array references to const pointers so not
  allowing mut references to mut pointers was inconsistent.

- mut array reference to const ptr. Example:

      let mut x: [usize; 2] = [0, 0];
      let p = &mut x as *const usize;

  This was similarly inconsistent as we allow casting mut references to
  const pointers.

Existing test 'vector-cast-weirdness' updated to test both cases.

Try fast_reject::simplify_type in coherence before doing full check

This is a reattempt at landing #69010 (by `@jonas-schievink).` The change adds a fast path for coherence checking to see if there's no way for types to unify since full coherence checking can be somewhat expensive.

This has big effects on code generated by the [`windows`](https://github.com/microsoft/windows-rs) which in some cases spends as much as 20% of compilation time in the `specialization_graph_of` query. In local benchmarks this took a compilation that previously took ~500 seconds down to ~380 seconds.

This is surely not going to make a difference on much smaller crates, so the question is whether it will have a negative impact. #69010 was closed because some of the perf suite crates did show small regressions.

Additional discussion of this issue is happening [here](https://rust-lang.zulipchat.com/#narrow/stream/247081-t-compiler.2Fperformance/topic/windows-rs.20perf).

Neither does it shorten the code nor does it provide a helpful name.

fde59a8cb7 Use Iterator::all instead of open-coding it
Shorter code and by initializing to the final value directly, the variable
doesn't need to be mut.

This hopefully should avoid future questions like in https://github.com/rust-lang/rust/pull/79979#issuecomment-776241356.

Rollup merge of #82011 - jyn514:warn-private-assoc-item, r=max-heller
Fix private intra-doc warnings on associated items

The issue was that the `kind, id` override was previously only being
considered for the disambiguator check, not the privacy check. This uses
the same ID for both.

Fixes https://github.com/rust-lang/rust/issues/81981.

Rollup merge of #82004 - GuillaumeGomez:clean-static-struct, r=jyn514
clean up clean::Static struct

Having a `String` for the expression didn't make much sense, and even less when it's actually not used (except in json so I kept it).

Rollup merge of #81997 - bnjbvr:dist-include-build-helper, r=Mark-Simulacrum
dist: include src/build_helper as part of the crate graph for rustc-dev

The build_helper dependency is used to build the compiler/rustc_llvm build script.

Since it was missing, it wasn't possible to really use rustc-dev to
build, see for instance: https://github.com/rust-analyzer/rust-analyzer/issues/7589.

Rollup merge of #81990 - matsujika:suggest-mut-reference, r=estebank
Make suggestion of changing mutability of arguments broader

Fix #81421

Previously rustc tries to emit the suggestion of changing mutablity unless `!trait_ref.has_infer_types_or_consts() && self.predicate_can_apply(obligation.param_env, trait_ref)` and this led to some false negatives to occur.

Rollup merge of #81955 - dtolnay:dwp, r=Mark-Simulacrum
bootstrap: Locate llvm-dwp based on llvm-config bindir

Fixes #81949.

Tested by successfully building 1.50.0 pre-release, which is where I originally hit the issue (https://internals.rust-lang.org/t/rust-1-50-0-pre-release-testing/14012/4?u=dtolnay). Tested both with and without prebuilt LLVM. The check for dry_run is necessary in the non-prebuilt case because the llvm-config built by bootstrap won't exist yet.
