357d53c4ce Introduce Constructor::NonExhaustive

matched exhaustively.

eb99c73e04 Match constructor first in Constructor methods
This makes it easier to add new non-standard constructors, and this also
ensures that we don't forget cases when adding a new constructor.

Rollup merge of #66309 - petrochenkov:annoying, r=Mark-Simulacrum
Tiny cleanup to size assertions

The need to write `#[cfg(target_arch = "x86_64")]` twice mildly annoys me, the full paths look better in comparison.

Rollup merge of #66299 - rossmacarthur:fix-41260-avoid-issue-0, r=varkor
support issue = "none" in unstable attributes

This works towards fixing #41260.

This PR allows the use of `issue = "none"` in unstable attributes and makes changes to internally store the issue number as an `Option<NonZeroU32>`. For example:

```rust
#[unstable(feature = "unstable_test_feature", issue = "none")]
fn unstable_issue_none() {}
```

It was not made optional because feedback seen here #60860 suggested that people might forget the issue field if it was optional.

I could not remove the current uses of `issue = "0"` (of which there are a lot) because the stage 0 compiler expects the old syntax. Once this is available in the stage 0 compiler we can replace all uses of `"0"` with `"none"` and no longer allow `"0"`. This is my first time contributing, so I'm not sure what the protocol is with two-part things like this, so some guidance would be appreciated.

Rollup merge of #66280 - stepancheg:union, r=alexcrichton
Fix HashSet::union performance

Consider this example: small_set = 0..2, large_set = 0..1000.

To efficiently compute the union of these sets, we should
* take all elements of the larger set
* for each element of the smaller set check it is not in the larger set

This is exactly what this commit does.

This particular optimization was implemented a year ago, but the
author mistaken `<` and `>`.

Rollup merge of #66257 - mati865:long-section-names-no-more, r=alexcrichton
Drop long-section-names linker workaround for windows-gnu

If we can trust objdump Rust doesn't emit sections loaded at runtime longer than 8 characters on windows-gnu (but still does on linux-gnu), debug sections are not affected by that limit.
I've ran tests and built few crates using exactly the same mingw-w64 version as Rusts CI just fine using **x86_64** toolchain.

The motivation for this change is making LLD work (it doesn't support `--enable-long-section-names`) with this target without hacks.

Bit of history:
The behaviour of LD changed in Binutils 2.20 released on 2009-10-16 and `--enable-long-section-names` was added to return to the old non conformant behaviour. Looking at the comment I can only guess there was a bug fixed in newer versions.

This workaround was added in https://github.com/rust-lang/rust/pull/13315 half a decade ago.

Rollup merge of #66230 - Axelderan:remove-vestigial-comments, r=alexcrichton
remove vestigial comments referring to defunct numeric trait hierarchy

I've been poking around the numeric trait hierarchy and also some of the actual numeric type implementations.

This is a small change but a matter of effective communication.  I looked for other related references and saw none.

e3d998492a Auto merge of #66129 - Nadrieril:refactor-slice-pat-usefulness, r=varkor
Refactor slice pattern usefulness checking

As a follow up to https://github.com/rust-lang/rust/pull/65874, this PR changes how variable-length slice patterns are handled in usefulness checking. The objectives are: cleaning up that code to make it easier to understand, and paving the way to handling fixed-length slices more cleverly too, for https://github.com/rust-lang/rust/issues/53820.

Before this, variable-length slice patterns were eagerly expanded into a union of fixed-length slices. Now they have their own special constructor, which allows expanding them a bit more lazily.
As a nice side-effect, this improves diagnostics.

This PR shows a slight performance improvement, mostly due to 149792b608. This will probably have to be reverted in some way when we implement or-patterns.

1aee3e4d08 Use a relative bindir for rustdoc to find rustc
In bootstrap, we set `RUSTC_INSTALL_BINDIR` to `config.bindir`, so
rustdoc can find rustc relative to the toolchain sysroot. However, if a
distro script like Fedora's `%configure` sets an absolute path, then
rustdoc's `sysroot.join(bin_path)` ignores that sysroot altogether.

That would be OK once the toolchain is actually installed, but it breaks
the in-tree doc tests during the build, since `/usr/bin/rustc` is still
the old version. So now we try to make `RUSTC_INSTALL_BINDIR` relative
to the sysroot prefix in the first place.

7320818292 Fix soundness issue with index bounds checks

for the inner index operation before evaluating the outer index. This
