Fix#78549
Before #78430, this worked because `specialize_constructor` didn't actually care too much which constructor was passed to it unless needed. That PR however handles `&str` as a special case, and I did not anticipate patterns for the `&str` type other than string literals.
I am not very confident there are not other similar oversights left, but hopefully only `&str` was different enough to break my assumptions.

Suggest calling associated `fn` inside `trait`s
When calling a function that doesn't exist inside of a trait's
associated `fn`, and another associated `fn` in that trait has that
name, suggest calling it with the appropriate fully-qualified path.
Expand the label to be more descriptive.
Prompted by the following user experience:
https://users.rust-lang.org/t/cannot-find-function/50663
Before #78430, string literals worked because `specialize_constructor`
didn't actually care too much which constructor was passed to it unless
needed. Since then, string literals are special cased and a bit hacky. I
did not anticipate patterns for the `&str` type other than string
literals, hence this bug. This makes string literals less hacky.
The validator in visit_local asserts that local has a stroage when used,
but visit_local is never called so validation is ineffective.
Use super_statement and super_terminator to ensure that locals are visited.

Avoid BorrowMutError with RUSTC_LOG=debug
```console
$ touch empty.rs
$ env RUSTC_LOG=debug rustc +stage1 --crate-type=lib empty.rs
```
Fails with a `BorrowMutError` because source map files are already
borrowed while `features_query` attempts to format a log message
containing a span.
Release the borrow before the query to avoid the issue.
Always record reference to binding in match if guards
When encountering a binding from a `match` pattern in its `if` guard when computing a generator's interior types, we must always record the type of a reference to the binding because of how `if` guards are lowered to MIR. This was missed in #75213 because the binding in that test case was autorefed and we recorded that adjusted type anyway.
Fixes#78366
Update Clippy - temporary_cstring_as_ptr deprecation
In #75671 `clippy::temporary_cstr_as_ptr` was removed instead of being deprecated. This will trigger an error (unknown lint) for users that refer to that lint to e.g. allow it, instead of a more informative warning.
This update should fix that for nightly users.

Include non-rustup artifacts in the manifest
This PR fixes https://github.com/rust-lang/promote-release/issues/22 by including all the files we ship in the generated manifests, even the ones that are not installable through rustup. In practice this adds the following "artifacts":
* `source-code`: the tarball containing the full source code used to build the release (`rustc-{channel}-src.tar.xz`)
* `installer-msi`: the MSI installer for Windows systems (`rust-{channel}-{target}.msi`)
* `installer-pkg`: the PKG installer for macOS systems (`rust-{channel}-{target}.pkg`)
These files are included in a new `artifacts` table of the manifest, like so:

```
Each artifact can be available for multiple targets, and each target can have multiple versions of the same file (for example, a `gz`-compressed one and a `xz`-compressed one). In the future rustup might add functionality to let users retrieve the artifacts, but that's not needed to land this PR, and whether to do the implementation is up to the rustup maintainers.

Even with `min_const_generics` active, now keeps resulting in future compat warnings instead of hard errors.
Const parameters, for example `[0; N + 1]`, still result in hard errors during resolve.

rustdoc options to set default theme (and other settings)
Hi. This is the MR I promised in #77024
It is a little more general than I envisaged there. Once I had found the settings-handling machinery it seemed foolish to add this feature just for the theme.
Closes#77024
Clarify main code paths in exhaustiveness checking
This PR massively clarifies the main code paths of exhaustiveness checking, by using the `Constructor` enum to a fuller extent. I've been itching to write it for more than a year, but the complexity of matching consts had prevented me. Behold a massive simplification :D.
This in particular removes a fair amount of duplication between various parts, localizes code into methods of relevant types when applicable, makes some implicit assumptions explicit, and overall improves legibility a lot (or so I hope). Additionally, after my changes undoing #76918 turned out to be a noticeable perf gain.
As usual I tried my best to make the commits self-contained and easy to follow. I've also tried to keep the code well-commented, but I tend to forget how complex this file is; I'm happy to clarify things as needed.
My measurements show good perf improvements on the two match-heavy benchmarks (-18.0% on `unicode_normalization-check`! :D); I'd like a perf run to check the overall impact.

This is a fairly simple special case of --default-eetting. We must
set both "theme" and "use-system-theme".
Providing it separately enables us to document a way to set the theme
without expoosing the individual settings keywords, which are quite
complex.
Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
We just plumb through what the user tells us.
This is flagged as unstable, mostly because I don't understand the
compatibility rules that rustdoc obeys for local storage data, and how
error handling of invalid data works.
We collect() the needed HashMap from Vec of Vecs of (key, value)
pairs, so that there is a nice place to add new more-specific options.
It would have been possible to use Extend::extend but doing it this
way ensures that all the used inputs are (and will stay) right next to
each other.
