On modern Linux with Intel AMX and 1KiB matrices,
Arm SVE with potentially 2KiB vectors,
and RISCV Vectors with up to 16KiB vectors,
we must handle dynamic signal stack sizes.

We can do so unconditionally by using getauxval,
but assuming it may return 0 as an answer,
thus falling back to the old constant if needed.
In rust-lang#121182 the mingw build was
changed to use MSYS2's version of Git. This commit reverts that, as
it was considered too slow.
- Fix invalid directive in `normalize-hidden-types`
- Update legacy directive in `two-phase-reservation-sharing-interference`
Add std::ffi::c_str module

ACP: rust-lang/libs-team#134

`std::ffi` docs before change:
![Structs: VaList, VaListImpl, CStr, CString, FromBytesWithNulError, FromVecWithNulError, IntoStringError, NulError, OsStr, OsString](https://github.com/rust-lang/rust/assets/15850505/b2cf3534-30f9-4ef0-a655-bacdc3a19e17)

`std::ffi` docs after change:
![Re-exports: self::c_str::{FromBytesWithNulError, FromBytesUntilNulError, FromVecWithNulError, NulError, IntoStringError} ; Modules: c_str ; Structs: VaList, VaListImpl, CStr, CString, OsStr, OsString](https://github.com/rust-lang/rust/assets/15850505/23aa6964-da7a-4942-bbf7-42bde2146f9e)

(note: I'm omitting the `c_int`, etc. stuff from the screenshots since it's the same in both. this doesn't just delete those types)

Dynamically size sigaltstk in std

On modern Linux with Intel AMX and 1KiB matrices,
Arm SVE with potentially 2KiB vectors,
and RISCV Vectors with up to 16KiB vectors,
we must handle dynamic signal stack sizes.

We can do so unconditionally by using getauxval,
but assuming it may return 0 as an answer,
thus falling back to the old constant if needed.

Fixes rust-lang#107795

Detect typos for compiletest test directives

Checks directives against a known list of compiletest directives collected during migration from legacy-style compiletest directives. A suggestion for the best matching known directive will be made if an invalid directive is found.

This PR does not attempt to implement checks for Makefile directives because they still have the problem of regular comments and directives sharing the same comment prefix `#`.

Closes rust-lang#83551.
…est_script, r=Mark-Simulacrum

Fixing shellcheck comments on lvi test script

Running `shellcheck` on `tests/run-make/x86_64-fortanix-unknown-sgx-lvi/script.sh` gives plenty of warnings. This PR fixes those issues. For completeness: rust-lang#121683 fixes another warning as well
Suggest correct path in include_bytes!

`include_bytes!` paths are relative, and I'm often not sure how nested is the `.rs` file that I'm editing, so I have to guess the number of `"../.."`. This change searches `..` and `../..` for the given file and offers corrected path as a suggestion.

I wasn't sure how to get the right span, and how to properly escape it.

```text
error: couldn't read src/file.txt: No such file or directory (os error 2)
 --> src/main.rs:2:13
  |
2 |     let x = include_bytes!("file.txt");
  |             ^^^^^^^^^^^^^^^----------^
  |                            |
  |                            help: it's in a parent directory: `"../../file.txt"`

Add a tidy check that checks whether the fluent slugs only appear once

As ``@Nilstrieb`` said in rust-lang#121828 (comment):
> Might make sense to have a tidy check that checks whether the fluent slugs only appear once in the source code and lint for that
there's a tidy check already for sorting

We can get the tidy check error:
```

Revert back to Git-for-Windows for MinGW CI builds

Following discussion in rust-lang#121182 it was decided to revert using MSYS2 Git for mingw builds.
match lowering: define a convenient struct

Small refactor PR: `bindings` and `ascriptions` always come together so I made a struct for them. I'll have one or two fields to add to it in a later PR as well.

Add test to check unused_lifetimes don't duplicate "parameter is never used" error

Closes rust-lang#72587.
add myself to rotation

Won't have too much capacity, but I am able to contribute something. Will be rotating reviews if I run out of capacity :)
