783879e6fe Partial no-op refactoring of #9948
This contains preparatory work for #9948 to keep that change to the
minimum, and make it easier to review it.

Migrate `format_args.rs` to `rustc_ast::FormatArgs`

changelog: none

Part of https://github.com/rust-lang/rust-clippy/issues/10233

Empty precision specifiers are no longer linted as the span for that isn't present in [`FormatOptions`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_ast/format/struct.FormatOptions.html)

```rust
format!("{:.}", ...)
```

That could be fixed later with some hackery or a change upstream

d57abf382b Rollup merge of #108548 - jamen:master, r=compiler-errors
Clarify the 'use a constant in a pattern' error message

```rs
use std::borrow::Cow;

const ERROR_CODE: Cow<'_, str> = Cow::Borrowed("23505");

fn main() {
    let x = Cow::from("23505");

    match x {
        ERROR_CODE => {}
    }
}
```
```
error: to use a constant of type `Cow` in a pattern, `Cow` must be annotated with `#[derive(PartialEq, Eq)]`
 --> src/main.rs:9:9
  |
9 |         ERROR_CODE => {}
  |         ^^^^^^^^^^

error: could not compile `playground` due to previous error
```

It seems helpful to link to StructuralEq in this message. I was a little confused, because `Cow<'_, str>` implements PartialEq and Eq, but they're not derived, which I learned is necessary for structural equality and using constants in patterns (thanks to the Rust community Discord server)

For tests, should I update every occurrence of this message? I see tests where this is still a warning and I'm not sure if I should update those.

538e8bdcc8 Rollup merge of #109354 - Swatinem:rm-closureid, r=compiler-errors
Remove the `NodeId` of `ast::ExprKind::Async`

This is a followup to https://github.com/rust-lang/rust/pull/104833#pullrequestreview-1314537416.

In my original attempt, I was using `LoweringContext::expr`, which was not correct as it creates a fresh `DefId`.
It now uses the correct `DefId` for the wrapping `Expr`, and also makes forwarding `#[track_caller]` attributes more explicit.

2493be2196 Improve is_range_full implementation
Make this function work with signed integer types by extracting the
underlying type and finding the min and max values.

Change the signature to make it more consistent:
- The range is now given as an `Expr` in order to extract the type
- The container's path is now passed, and only as an `Option` so that
  the function can be called in the general case without a container

00e9372987 Auto merge of #10516 - Alexendoo:split-debuginfo, r=flip1995
Use `split-debuginfo = "unpacked"` for debug builds

On Windows this has no effect as it's unsupported. On macOS the default set by cargo is already unpacked so no effect there either

For Linux it shaves a bit off the rebuild time, for me in the case of a simple `touch` + `cargo build` it goes from 12s to 10s

It saves a good amount of disk space too, on `aarch64-unknown-linux-gnu` it saves 1.2GB for a plain `cargo build`, 3GB when also running `cargo dev` and `cargo test --no-run -F internal`

Significantly optimize `significant_drop_tightening`

The lint is very slow as it doesn't cache the deeply nested check for the attribute. If we cache it, we can reduce the time spent on checking `rustc_borrowck` from 28s to 9s, which is a nice improvement. In the profile, the time inside `has_sig_drop_attr` goes from 66% to 0.2%, which is a lot more reasonable.
