Use tracing spans in rustc_trait_selection
Spans are very helpful when debugging this code. It's also hot enough to make a good benchmark.

Mono collector: replace pair of ints with Range
I found the initial PR (#33171) that introduced this piece of code but I didn't find any information about why a tuple was preferred over a `Range<usize>`.
I'm hoping there are no technical reasons to not do this.
Implement `AsRawFd` for `StdinLock` etc. on WASI.
WASI implements `AsRawFd` for `Stdin`, `Stdout`, and `Stderr`, so
implement it for `StdinLock`, `StdoutLock`, and `StderrLock` as well.

This commit changes the way build-manifest is invoked, to let it accept
the Rust version directly instead of requiring the path of the Rust
monorepo and letting build-manifest figure out the path on its own.
This allows to run build-manifest without a clone of the monorepo.
build-manifest: stop generating numbered channel names except for stable
This fixes numbered channel names being created for the nightly channel, and once the root cause of this rides the trains, for beta.

Remove unnecessary unsafe block around calls to discriminant_value
Since 63793 the discriminant_value intrinsic is safe to call. Remove
unnecessary unsafe block around calls to this intrinsic in built-in
derive macros.
During the document coverage reporting with
```bash
rustdoc something.rs -Z unstable-options --show-coverage
```
the coverage report also includes parts of the code that are marked
with `#[allow(missing_docs)]`, which outputs lower numbers in the
coverage report even though these parts should be ignored for the
calculation.

Promote aarch64-pc-windows-msvc to Tier 2 Development Platform
Adds a GitHub Actions CI build for `aarch64-pc-windows-msvc` via cross-compilation on an x86_64 host.
This promotes `aarch64-pc-windows-msvc` from a Tier 2 Compilation Target (std) to a Tier 2 Development Platform (std+rustc+cargo+tools).
Fixes#72881

Fix -Clinker-plugin-lto with opt-levels s and z
Pass s and z as `-plugin-opt=O2` to the linker. This is what `-Os` and `-Oz` correspond to, apparently.
Fixes https://github.com/rust-lang/rust/issues/75940
This stabilizes the functionality in slice_partition_at_index,
but under the names `select_nth_unstable*`. The functions
`partition_at_index*` are left as deprecated, to be removed in
a later release.
Closes#55300
