On stable, our artifacts are uploaded with the raw version number (e.g.,
1.65.0), not the channel. This adjusts our detection logic to use the
version number from src/version when we detect the stable channel.

There is a layout change caused by this commit, but it's subtle. You won't
notice it unless you're looking for it.

Fix artifact version/channel detection for stable

On stable, our artifacts are uploaded with the raw version number (e.g., 1.65.0), not the channel. This adjusts our detection logic to use the version number from src/version when we detect the stable channel.

This is really only important for stable channel re-builds, I think, but those do happen from time to time. I'm backporting a similar commit in rust-lang#103859 to make that PR pass CI.

Cleanup bind_pattern args

Fixes rust-lang#101896

Make mir opt unused file check blessable

Makes it slightly nicer to work with.

Can't write automated test but tested locally via

```
$ touch src/test/mir-opt/random
$ x test tidy // shows failure
$ x test tidy --bless // file gone
```

LLVM 16: Switch to using MemoryEffects

This adapts the compiler to the changes required by llvm/llvm-project@304f1d5.

AFAICT, `WriteOnly` isn't used by the compiler, all `ReadNone` uses were migrated and the remaining use of `ReadOnly` is only for function parameters.

To simplify the FFI, this PR uses an enum to represent `MemoryEffects` across the FFI boundary, which then gets mapped to the matching static factory method when constructing the attribute.

Fixes rust-lang#103961.
