Introduce a no-op `PlaceMention` statement for `let _ =`.
Fixes https://github.com/rust-lang/rust/issues/54003
Fixes https://github.com/rust-lang/rust/issues/80059
Split from https://github.com/rust-lang/rust/pull/101500
This PR introduces a new `PlaceMention` statement dedicated to matches that neither introduce bindings nor ascribe types. Without this, all traces of the match would vanish from MIR, making it impossible to diagnose unsafety or use in #101500.
This allows to mark `let _ = <unsafe union access or dereference>` as requiring an unsafe block.
Nominating for lang team, as this introduces an extra error.
Fix the docs for pointer method with_metadata_of
The name of the argument to `{*const T, *mut T}::with_metadata_of` was changed from `val` to `meta` recently, but the docs weren't updated to match.

Remove `body_def_id` from `Inherited`
We can just use the body id from the obligation cause.
Follow-up to #108945, only my commit is relevant.

Document the resulting values produced when using `From<bool>` on floats
Have the documentation of the implementation of `From<bool>` on `f32` and `f64` indicate the output values (`0.0` for `false` and `1.0` for `true`).

Unconstrained terms should account for infer vars being equated
Follow-up from the canonicalization PR, wanted to break this one out so I can approve the other PR.

Migrate `write.rs` to `rustc_ast::FormatArgs`
changelog: none
Part 1 of #10233
The additions to `clippy_utils` are the main novelty of this PR, there's no removals yet since other parts still rely on `FormatArgsExpn`
The changes to `write.rs` itself are relatively straightforward this time around, as there's no lints in it that rely on type checking format params
r? `@flip1995`
Mark Rust 1.68.0 as release in the changelog
Roses are red,
this poem is dead,
my creativity is lost,
outside there is frost?
Maybe I should really stop including a "roses are red" with every changelog PR. These are getting worse every time...

internal: Don't attempt to calculate diagnostics in library crates
We already filtered these later on, but we might as well stop calculating them alltogether. This way we also show cargo diagnostics that occur outside of the workspace which can happen when something goes very wrong (and which usually then causes no check diagnostics to appear in the workspace at all)

This is fixed by simply using the currently registered target in the
current session. We need to use it because of target json that are not
by design included in the rustc list of targets.
