`@!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.

For the most part, the macro actually worked with _ slugs, but the prefix_something -> prefix::something
conversion was not implemented.
We don't want to accept - slugs for consistency reasons.
We thus error if a name is found with - inside.
This ensures a consistent style.
Having to replace - with _ (and vice versa) makes the slugs less greppable
and thus constitutes a contributor roadblock.
Result of running this repeatedly up until reaching a fixpoint:
find compiler/rustc_error_messages/locales/en-US/ -type f -exec sed -i 's/\(.+\)-\(.*\)=/\1_\2=/' {} \;
Plus some fixes to update usages of slugs leading with -.

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.

Make `Name` hold escaped name
Resolves#12787Resolvesrust-lang/rust#99361
This PR effectively swaps `Name` and `EscapedName` in hir. In other words, it makes `Name` hold and print escaped raw identifiers and introduces another struct `UnescapedName` for cases where you need to print names without "r#" prefix.
My rationale is that it makes it easier for us to format an escaped name into string, which is what we want when we serialize names in general. This is because we format a name into string usually when we are presenting it to the users and arguably they expect its escaped form as that's what they see and write in the source code.
I split the change for `Name` into 3 commits to make it easier to follow but it also made some tests fail in the intermediate commits. I can squash them into a commit after the review if desired. I've also made similar changes for `ModPath` and `EscapedModPath` as it makes them consistent with `Name`.
For reference, there was a brief discussion on this in [a zulip thread](https://rust-lang.zulipchat.com/#narrow/stream/185405-t-compiler.2Frust-analyzer/topic/escaping.20.60Name.60s).
passes: load `defined_lib_features` query less
Hopefully addresses the perf regressions from #99212 (see #99905).
Re-structure the stability checks for library features to avoid calling `defined_lib_features` for any more crates than necessary for each of the implications or local feature attributes that need validation.
r? `@ghost` (just checking perf at first)
