doc: disambiguate stat in MetadataExt::as_raw_stat
A few architectures in `os::linux::raw` import `libc::stat`, rather than
defining that type directly. However, that also imports the _function_
called `stat`, which makes this doc link ambiguous:
error: `crate::os::linux::raw::stat` is both a struct and a function
--> library/std/src/os/linux/fs.rs:21:19
|
21 | /// [`stat`]: crate::os::linux::raw::stat
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^ ambiguous link
|
= note: `-D broken-intra-doc-links` implied by `-D warnings`
help: to link to the struct, prefix with the item type

21 | /// [`stat`]: struct@crate::os::linux::raw::stat
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
help: to link to the function, add parentheses
|
21 | /// [`stat`]: crate::os::linux::raw::stat()
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
We want the `struct`, so it's now prefixed accordingly.
Clarify the debug-related values should take boolean
#76588 tweaked their placeholders but these values should take boolean and the current placeholders are confusing, at least for me.
Add TraitDef::find_map_relevant_impl
This PR adds a method to `TraitDef`. While `for_each_relevant_impl` covers the general use case, sometimes it's not necessary to scan through all the relevant implementations, so this PR introduces a new method, `find_map_relevant_impl`. I've also replaced the `for_each_relevant_impl` calls where possible.
I'm hoping for a tiny bit of efficiency gain here and there.
fix __rust_alloc_error_handler comment
`__rust_alloc_error_handler` was added in the same `extern` block as the allocator functions, but the comment there was not actually correct for `__rust_alloc_error_handler`. So move it down to the rest of the default allocator handling with a fixed comment. At least the comment reflects my understanding of what happens, please check carefully. :)

Cleanup of `eat_while()` in lexer
The size of a lexer Token was inflated by the largest `TokenKind` variants `LiteralKind::RawStr` and `RawByteStr`, because
* it used `usize` although `u32` is sufficient in rustc, since crates must be smaller than 4GB,
* and it stored the 20 bytes big `RawStrError` enum for error reporting.
If a raw string is invalid, it now needs to be reparsed to get the `RawStrError` data, but that is a very cold code path.
Technically this breaks other tools that depend on rustc_lexer because they are now also restricted to a max file size of 4GB. But this shouldn't matter in practice, and rustc_lexer isn't stable anyway.
Can I also get a perf run?
Edit: This makes no difference in performance. The PR now only contains a small cleanup.
Link to documentation-specific guidelines.
Changed contribution information URL because it's not obvious how to get from the current URL to the documentation-specific content.
The current URL points to this "Getting Started" page, which contains nothing specific about documentation[*] and instead launches into how to *build* `rustc` which is not a strict prerequisite for contributing documentation fixes:
* https://rustc-dev-guide.rust-lang.org/getting-started.html
[*] The most specific content is a "Writing documentation" bullet point which is not itself a link to anything (I guess a patch for that might be helpful too).
### Why?
Making this change will make it easier for people who wish to make small "drive by" documentation fixes (and read contribution guidelines ;) ) which I find are often how I start contributing to a project. (Exhibit A: https://github.com/rust-lang/rust/pull/77050 :) )
### Background
My impression is the change of content linked is an unintentional change due to a couple of other changes:
* Originally, the link pointed to `contributing.md` which started with a "table of contents" linking to each section. But the content in `contributing.md` was removed and replaced with a link to the "Getting Started" section here:
* 3f6928f1f6 (diff-6a3371457528722a734f3c51d9238c13L1)
But the changed link doesn't actually point to the equivalent content, which is now located here:
* https://rustc-dev-guide.rust-lang.org/contributing.html
(If the "Guide to Rustc Development" is now considered the canonical location of "How to Contribute" content it might be a good idea to merge some of the "Contributing" Introduction section into the "Getting Started" section.)
* This was then compounded by changing the link from `contributing.md` to `contributing.html` here:
* https://github.com/rust-lang/rust/pull/74037/files#diff-242481015141f373dcb178e93cffa850L88
In order to even find the new location of the previous `contributing.md` content I ended up needing to do a GitHub search of the `rust-lang` org for the phrase "Documentation improvements are very welcome". :D

cc #76839
This got out of sync when the version was bumped last time.
Long-term we may want to find an easier way to maintain this that
doesn't require bumping the version in three different places. Off the
top of my head I can't think of anything, though.

rustc_target: Refactor away `TargetResult`
Follow-up to https://github.com/rust-lang/rust/pull/77202.
Construction of a built-in target is always infallible now, so `TargetResult` is no longer necessary.
The second commit contains some further cleanup based on built-in target construction being infallible.
Always use the Rust version in package names
The format of the tarballs produced by CI is roughly the following:
{component}-{release}-{target}.{ext}
While on the beta and nightly channels `{release}` is just the channel name, on the stable channel is either the Rust version or the version of the component we're shipping:
cargo-0.47.0-x86_64-unknown-linux-gnu.tar.xz
clippy-0.0.212-x86_64-unknown-linux-gnu.tar.xz
llvm-tools-1.46.0-x86_64-unknown-linux-gnu.tar.xz
miri-0.1.0-x86_64-unknown-linux-gnu.tar.xz
rls-1.41.0-x86_64-unknown-linux-gnu.tar.xz
rust-1.46.0-x86_64-unknown-linux-gnu.tar.xz
...
This makes it really hard to get the package URL without having access to the manifest (and there is no manifest on ci-artifacts.rlo), as there is no consistent version number to use.
This PR addresses the problem by always using the Rust version number as `{release}` for the stable channel, regardless of the version number of the component we're shipping. I chose that instead of "stable" to avoid breaking the URL scheme *that* much.
Rustup should not be affected by this change, as it fetches the URLs from the manifest. Unfortunately we don't have a way to test other clients before making a stable release, as this change only affects the stable channel.

Warn on broken intra-doc links added to cross-crate re-exports
This emits `broken_intra_doc_links` for docs applied to pub use statements that point to external items and are inlined.
Does not address #77200 - any existing broken links from the original crate will not show warnings.
