This can append if within the same module a `#[macro_export] macro_rules!`
is declared but also a reexport of itself producing two export of the same
macro in the same module. In that case we only want to document it once.

HermitCore's kernel itself doesn't support TLS.
Consequently, the entries in x86_64-unknown-none-hermitkernel should be removed.
This commit should help to finalize rust-lang#89062.

No functional changes intended.

The LLVM commit
llvm/llvm-project@89b5706
moved TargetRegistry.(h|cpp) from Support to MC.
This adapts RustWrapper accordingly.

This reverts commit 36a1076, reversing
changes made to e1e9319.

The affected crates have had plenty of time to update.
By keeping these as lints rather than making them hard errors,
we ensure that downstream crates will still be able to compile,
even if they transitive depend on broken versions of the affected
crates.

This should hopefully discourage anyone from writing any
new code which relies on the backwards-compatibility behavior.

Fix macro_rules! duplication when reexported in the same module

This can append if within the same module a `#[macro_export] macro_rules!`
is declared but also a reexport of itself producing two export of the same
macro in the same module. In that case we only want to document it once.

Before:
```
Module {
    is_crate: true,
    items: [
        Id("0:4"),   // pub use crate::repro as repro2;
        Id("0:3"),   // macro_rules! repro
        Id("0:3"),   // duplicate, same as above
    ],
}
```

After:
```
Module {
    is_crate: true,
    items: [
        Id("0:4"),   // pub use crate::repro as repro2;
        Id("0:3"),   // macro_rules! repro
    ],
}
```

Fixes rust-lang#89852

Suggest a case insensitive match name regardless of levenshtein distance

Fixes rust-lang#86170

Currently, `find_best_match_for_name` only returns a case insensitive match name depending on a Levenshtein distance. It's a bit unfortunate that that hides some suggestions for typos like `Bar` -> `BAR`. That idea is from rust-lang#46347 (comment), but I think it still makes some sense to show a candidate when we find a case insensitive match name as it's more like a typo.
Skipped the `candidate != lookup` check because the current (i.e, `levenshtein_match`) returns the exact same `Symbol` anyway but it doesn't seem to confuse anything on UI tests.
