Erase regions better in `promote_candidate`
Use `tcx.erase_regions` instead of manually walking through the substs.... this also makes the code slightly simpler 🙈Fixes#100360Fixes#89851
`@!has` (and `@!matches`) with two arguments used to treat the second
argument as a literal string of HTML code. Now, that feature has been
renamed into `@!hasraw` (and `@!matchesraw`), and the arity-2 `@!has`
version is an error.
These uses thought the second argument was being treated as an XPath, as
with the arity-3 version, but in fact was being treated as literal HTML.
Because these were checking for the *absence* of the string, the tests
silently did nothing -- an XPath string won't ever be showing up in the
test's generated HTML!
Reasons:
1. It's shorter.
2. `@matches-literal` seems to contradict itself: a regex is
intrinsically not a literal match, while it is still a textual match.
Use llvm-libunwind="in-tree" for Fuchsia targets
With updates to Fuchsia CI's Zircon libraries #99833, we can introduce `llvm-libunwind="in-tree"` for Fuchsia targets. This PR restores functionality removed from https://github.com/rust-lang/rust/pull/93604#issuecomment-1136515651.

Add two let else regression tests
Adds a regression test for #94176, as it was fixed by #98574 but doesn't have a regression test. The PR also incorporates a commit from #94012 which added a test for an issue discovered in that PR.
Originally they have been part of #99291, but I've moved them out in the hopes of getting them merged more quickly, as that PR is already open since a month, and so that #99291 can focus on the drop order part of things.

errors: don't fail on broken primary translations
If a primary bundle doesn't contain a message then the fallback bundle is used. However, if the primary bundle's message is broken (e.g. it refers to a interpolated variable that the compiler isn't providing) then this would just result in a compiler panic. While there aren't any primary bundles right now, this is the type of issue that could come up once translation is further along.

Generalize trait object generic param check to aliases.
The current algorithm only checks that `Self` does not appear in defaults for traits. This is not sufficient for trait aliases.
This PR moves the check to trait object elaboration, which sees through trait aliases.

Update to LLVM 15
For preliminary testing. Some LLVM 15 compatibility fixes were applied separately in #99512.
Release timeline:
* LLVM 15 branched on Jul 26.
* The final LLVM 15.0.0 release is scheduled for Sep 6.
* Current nightly (1.65.0) is scheduled for Nov 3.
Changes in this PR (apart from the LLVM update):
* Pass `--set llvm.allow-old-toolchain` for many Docker images. LLVM 16 will require GCC >= 7.1, while LLVM 15 still allows older compilers with an option. Specify the option for builders still using GCC 5.4. #95026 updated some of the used toolchains, but not all.
* Use the `+atomics-32` target feature for thumbv6m.
* Explicitly link libatomic when cross-compiling LLVM to 32-bit target.
* Explicitly disable zstd support, to avoid libzstd.so dependency.
New LLVM patches ([commits](https://github.com/rust-lang/llvm-project/commits/rustc/15.0-2022-08-09)):

In our source page highlighting, we were generating `<span class="op">`
tags for all "operators", including e.g. `<` `>` around generic
parameters, `*`, `&`. This contributed significantly to DOM size, but
we don't actually style `.op` except in the ayu theme.
Remove the styles for `.op` in ayu, and stop generating the `<span>`s.
This reduces DOM size of an example page[1] from 265,938 HTML elements
to 242,165 elements, a 9% reduction.

Stringify non-shorthand visibility correctly
This makes `stringify!(pub(in crate))` evaluate to `pub(in crate)` rather than `pub(crate)`, matching the behavior before the `crate` shorthand was removed. Further, this changes `stringify!(pub(in super))` to evaluate to `pub(in super)` rather than the current `pub(super)`. If the latter is not desired (it is _technically_ breaking), it can be undone.
