migration lint for `expr2024` for the edition 2024

This is adding a migration lint for the current (in the 2021 edition and previous)
to move expr to expr_2021 from expr

Issue rust-lang#123742

I created also a repository to test out the migration https:/vincenzopalazzo/expr2024-cargo-fix-migration

Add `powerpc-unknown-openbsd` maintaince status

As noted in rust-lang#126451 (comment) `powerpc-unknown-openbsd` is not maintained by the OpenBSD devs. If a maintainer is found this can be updated with their information but we should document the current status and note explicitly that it's different from other OpenBSD targets.
Print the tested value in int_log tests

Tiny change - from the failures in rust-lang#125016, it would have been nice to see what the tested values were. Update the assertion messages.
Expand `avx512_target_feature` to include VEX variants

Added 5 new target features for x86:

 - `AVX-IFMA`
 - `AVX-NE-CONVERT`
 - `AVX-VNNI`
 - `AVX-VNNI_INT8`
 - `AVX-VNNI_INT16`

Both LLVM and GCC already have support for these.

See also the [stdarch PR](rust-lang/stdarch#1586)
…=compiler-errors

Add `#[rustc_dump_{predicates,item_bounds}]`

Conflicts with rust-lang#126668.

As discussed
r? compiler-errors CC `@fee1-dead`
Make edition dependent `:expr` macro fragment act like the edition-dependent `:pat` fragment does

Parse the `:expr` fragment as `:expr_2021` in editions <=2021, and as `:expr` in edition 2024. This is similar to how we parse `:pat` as `:pat_param` in edition <=2018 and `:pat_with_or` in >=2021, and means we can get rid of a span dependency from `nonterminal_may_begin_with`.

Specifically, this fixes a theoretical regression since the `expr_2021` macro fragment previously would allow `const {}` if the *caller* is edition 2024. This is inconsistent with the way that the `pat` macro fragment was upgraded, and also leads to surprising behavior when a macro *caller* crate upgrades to edtion 2024, since they may have parsing changes that they never asked for (with no way of opting out of it).

This PR also allows using `expr_2021` in all editions. Why was this was disallowed in the first place? It's purely additive, and also it's still feature gated?

Pass target to inaccessible-temp-dir rmake test

This PR circles back to do the target specific changes in `inaccessible-temp-dir` from rust-lang#126355. Specifically, this repairs the test on `riscv64gc-unknown-linux-gnu`. (The failure can be viewed in rust-lang#126641 -> https:/rust-lang/rust/actions/runs/9571149616/job/26387537888?pr=126641)

We removed this change from rust-lang#126355 to avoid a merge conflict with rust-lang#126279. (...and, because I hoped that would fix the test instead, but it did not.)

## Testing

> [!NOTE]
> `riscv64gc-unknown-linux-gnu` is a [**Tier 2 with Host Tools** platform](https://doc.rust-lang.org/beta/rustc/platform-support.html), all tests may not necessarily pass! This PR is specifically about the `inaccessible-temp-dir` rmake test.

You can test out the job locally:

```sh
DEPLOY=1 ./src/ci/docker/run.sh riscv64gc-gnu
```

`DEPLOY=1` helps reproduce the CI's environment and also avoids the chance of a `llvm-c/BitReader.h` error (detailed in rust-lang#85424 and rust-lang#56650).

Properly gate `safe` keyword in pre-expansion

This PR gates `safe` keyword in pre-expansion contexts. Should mitigate the fallout of rust-lang#126755, which is that `safe` is now usable on beta lol.
