Update minifier dependency version
Very small PR simply upgrading the minifier-rs version we use in rustdoc.
Some details might be useful: there were a few bug fixes and a lot of cleanup/code improvements.

Refactor types lints
Ref #6724.
As described in #6724, `types.rs` contains many groups inside it.
In this PR, I reorganize the lints of the `types` group into their own modules.

Let Cargo track CLIPPY_ARGS
This PR makes `clippy-driver` emit `CLIPPY_ARGS` in its `dep-info` output.
Just like #6441, this allows this workflow to work:
```shell
cargo clippy # warning: empty `loop {}` wastes CPU cycles
cargo clippy -- -A clippy::empty_loop # no warnings emitted
```
But without rebuilding all dependencies.

changelog: Cargo now re-runs Clippy if arguments after `--` provided to `cargo clippy` are changed.
Generalize Write impl for Vec<u8> to Vec<u8, A>
As discussed in the [issue tracker for the wg-allocators working group][1], updating this impl for allocator support was most likely just forgotten previously. This PR fixes this.

Refactor confirm_builtin_call, remove partial if
Pass callee expr to `confirm_builtin_call`. This removes a partial
pattern match in `confirm_builtin_call` and the `panic` in the `else`
branch. The diff is large because of indentation changes caused by
removing the if-let.
Disable destination propagation on all mir-opt-levels
The new `// compile-flags: -Zunsound-mir-opts` are inserted without an extra newline to avoid introducing a large mir-opt diff.
Implement built-in attribute macro `#[cfg_eval]` + some refactoring
This PR implements a built-in attribute macro `#[cfg_eval]` as it was suggested in https://github.com/rust-lang/rust/pull/79078 to avoid `#[derive()]` without arguments being abused as a way to configure input for other attributes.
The macro is used for eagerly expanding all `#[cfg]` and `#[cfg_attr]` attributes in its input ("fully configuring" the input).
The effect is identical to effect of `#[derive(Foo, Bar)]` which also fully configures its input before passing it to macros `Foo` and `Bar`, but unlike `#[derive]` `#[cfg_eval]` can be applied to any syntax nodes supporting macro attributes, not only certain items.
`cfg_eval` was the first name suggested in https://github.com/rust-lang/rust/pull/79078, but other alternatives are also possible, e.g. `cfg_expand`.
```rust
#[cfg_eval]
#[my_attr] // Receives `struct S {}` as input, the field is configured away by `#[cfg_eval]`
struct S {
#[cfg(FALSE)]
field: u8,
}
```

Remove Item::kind, use tagged enum. Rename variants to match
Fixes#82299, by making the ItemEnum tagged. Doesn't remove ItemKind as it's still used in other places.

Add natvis for Result, NonNull, CString, CStr, and Cow
This adds natvis support (used for Windows debugging) to the following types: `Result`, `NonNull`, `CString`, `CStr`, and `Cow`.
expand: Refactor module loading
This is an accompanying PR to https://github.com/rust-lang/rust/pull/82399, but they can be landed independently.
See individual commits for more details.
Anyone should be able to review this equally well because all people actually familiar with this code left the project.
bypass auto_da_alloc for metadata files
This saves about 0.7% when rerunning the UI test suite. I.e. when the metadata files exist and will be overwritten. No improvements expected for a clean build. So it might show up in incr-patched perf results.
```
regular rename:
Benchmark #1: touch src/tools/compiletest/src/main.rs ; RUSTC_WRAPPER="" schedtool -B -e ./x.py test src/test/ui
Time (mean ± σ): 47.305 s ± 0.170 s [User: 1631.540 s, System: 412.648 s]
Range (min … max): 47.125 s … 47.856 s 20 runs
non-durable rename:
Benchmark #1: touch src/tools/compiletest/src/main.rs ; RUSTC_WRAPPER="" schedtool -B -e ./x.py test src/test/ui
Time (mean ± σ): 46.930 s ± 0.064 s [User: 1634.344 s, System: 396.038 s]
Range (min … max): 46.759 s … 47.043 s 20 runs
```
There are more places that trigger auto_da_alloc behavior by overwriting existing files with O_TRUNC, but those are much harder to locate because `O_TRUNC` is set on `open()` but the writeback is triggered on `close()`. The latter is the part which shows up in profiles.
Backport some LLVM compile-time improvements
Pick up two LLVM patches that reduce number of alias analysis queries, to see whether that gives any visible improvement.
