macros: diagnostic derive on enums
Part of #100717.
Extends `#[derive(Diagnostic)]` to work on enums too where each variant acts like a distinct diagnostic - being able to represent diagnostics this way can be quite a bit simpler for some parts of the compiler.

The doc comment for [splitn](https://github.com/rust-lang/rust/blob/master/library/core/src/slice/mod.rs#L2051:L2056) is the exact same as the comment for [splitn_mut](https://github.com/rust-lang/rust/blob/master/library/core/src/slice/mod.rs#L2079:L2084). The doc comment for `splitn_mut` should instead say it's working on a mutable subslice.

Allow more `!Copy` impls
You can already implement `!Copy` for a lot of types (with `#![feature(negative_impls)]`). However, before this PR you could not implement `!Copy` for ADTs whose fields don't implement `Copy` which didn't make any sense. Further, you couldn't implement `!Copy` for types impl'ing `Drop` (equally nonsensical).
Auto merge of #102257 - cjgillot:let-else-lint, r=dingxiangfei2009
Fix lint scoping for let-else.
The scoping for let-else is inconsistent with HIR nesting. This creates cases, in `ui/let-else/let-else-allow-unused.rs` for instance, where an `allow` lint attribute does not apply to the bindings created by `let-else`.
This PR is an attempt to correct this.
As there is no lint that currently relies on this, the test for this behaviour is https://github.com/rust-lang/rust/pull/101500.

Stabilize const `BTree{Map,Set}::new`
The FCP was completed in #71835.
Since `len` and `is_empty` are not const stable yet, this also creates a new feature for them since they previously used the same `const_btree_new` feature.
* Remove the `float: right` fallback from the main header, which hasn't been needed since IE11 support was dropped.
* Remove `in-band` from low-level headers, which hasn't been needed since `.rightside` switched to `float: right` in https://github.com/rust-lang/rust/commit/593d6d1cb15c55c88319470dabb40126c7b7f1e2
* Remove unreachable `.in-band > code, .in-band > .code-header` CSS, since the `in-band` class was attached to the `code-header` itself, not nested directly below it.
* Use `rem` instead of `em` for code header margins.
* This results in a slight change in spacing around impls and item-info, but since it makes it more consistent with the way methods are presented, it's probably fine.

It also improves a number of proc macro diagnostics.

Remove support for legacy PM
This removes support for optimizing with LLVM's legacy pass manager, as well as the unstable `-Znew-llvm-pass-manager` option. We have been defaulting to the new PM since LLVM 13 (except for s390x that waited for 14), and LLVM 15 removed support altogether. The only place we still use the legacy PM is for writing the output file, just like `llc` does.

Rollup merge of #98111 - eggyal:issue-97982, r=GuillaumeGomez
Clarify `[T]::select_nth_unstable*` return values
In cases where the nth element is not unique within the slice, it is not
correct to say that the values in the returned triplet include ones for
"all elements" less/greater than that at the given index: indeed one (or
more) such values would then also contain elements equal to that at
the given index.
The text proposed here clarifies exactly what is returned, but in so
doing it is also documenting an implementation detail that previously
wasn't detailed: namely that the returned slices are slices into the
reordered slice. I don't think this can be contentious, because the
lifetimes of those returned slices are bound to that of the original
(now reordered) slice—so there really isn't any other reasonable
implementation that could have this behaviour; but nevertheless it's
probably best if `@rust-lang/libs-api` give it a nod?
Auto merge of #100865 - compiler-errors:parent-substs-still, r=cjgillot
Don't drop parent substs when we have no generic parameters in `create_substs_for_ast_path`
This bug is being shadowed by an explicit check for `generics.params.is_empty()` in the only parent caller that could trigger it (`create_substs_for_associated_item`). I triggered it on another branch where I'm messing around with astconv stuff.
Also, the second commit simplifies `create_substs_for_associated_item`. Removing that explicit check I mentioned above^ and also the special case call to `Astconv::prohibit_generics` causes the UI test `src/test/ui/structs/struct-path-associated-type.stderr` to change, but I think that it's clearer now. The suggestion to remove the generics is actually useful.
