Add more `// unit-test`s to MIR opt tests
I only changed things which are hopefully completely uninteresting. I plan to submit more PRs that cover more files, but those cases will need some more complicated (and hence possibly controversial) changes, so I'll try and submit those in reasonably sized batches.

Add error if link_ordinal used with unsupported link kind
The `link_ordinal` attribute only has an affect if the `raw-dylib` link kind is used, so add an error if it is used with any other link kind.
Stabilize backtrace
This PR stabilizes the std::backtrace module. As of #99431, the std::Error::backtrace item has been removed, and so the rest of the backtrace feature is set to be stabilized.
Previous discussion can be found in #72981, #3156.
Stabilized API summary:
```rust
pub mod std {
pub mod backtrace {
pub struct Backtrace { }
pub enum BacktraceStatus {
Unsupported,
Disabled,
Captured,
}
impl fmt::Debug for Backtrace {}
impl Backtrace {
pub fn capture() -> Backtrace;
pub fn force_capture() -> Backtrace;
pub const fn disabled() -> Backtrace;
pub fn status(&self) -> BacktraceStatus;
}
impl fmt::Display for Backtrace {}
}
}
```

For some reason, adding some text to match against makes this test pass.
Before, when it was *more* general, it was failing!
This seems very likely to be a bug in htmldocck, which I'm going to
investigate.

`@rustbot` modify labels: rollup
Split render_with_highlighting, which took many optional parameters, into three
functions for specific purposes, which each take a smaller number of mostly
required parameters.
Remove some plumbing to pass through an "edition" parameter, which was used
solely to avoid highlighting some 2021 Edition keywords in non-2021 code.
Set tainted errors bit before emitting coerce suggestions.
Fixes#100246.
#89576 basically got 99% of the way there but the match typechecking code (which calls `coerce_inner`) also needed a similar fix.
Add some high-level docs to `FnCtxt` and `ItemCtxt`
I haven't understood the difference between these before, but
``@compiler-errors`` helped me clear it up. Hopefully this will help other
people who've been confused!

Some "this expression has a field"-related fixes
Each commit does something different and is worth reviewing, but the final diff from `master..HEAD` contains the sum of the changes to the UI tests, since some commits added UI tests "regressions" which were later removed in other commits.
The only change I could see adding on top of this is suppressing `Clone::clone` from the "this expression has a field that has this method" suggestion, since it's so commonly implemented by types that it's not worthwhile suggesting in general.
linker-plugin-lto.md: Correct the name of example c file
The final output is linked with `cmain.o`, but we use `main.o` in the example.
This patch changes the name to `cmain.c` and `cmain.o` as the "C/C++ code as a dependency in Rust" section.
Error on broken pipe but do not backtrace or ICE
Windows will report a broken pipe as a normal error which in turn `println!` will panic on. Currently this causes rustc to produce a backtrace and ICE. However, this is not a bug with rustc so a backtrace is overly verbose and ultimately unhelpful to the user.
Kind of fixes#98700. Although this is admittedly a bit of a hack because at panic time all we have is a string to inspect. On zulip it was suggested that libstd might someday provide a way to indicate a soft panic but that day isn't today.
rustdoc-json: Remove doc FIXME for Import::id and explain
Also add some test and refactor related code a bit.

rustdoc: improve scroll locking in the rustdoc mobile sidebars
This PR prevents the main content area from scrolling while the mobile sidebar is open on documentation pages (porting the scroll locking behavior from the source sidebar to the regular sidebar), and also fixes some bad behavior where opening a "mobile" sidebar, and growing the viewport so that the "desktop" mode without scroll locking is activated, could potentially leave the page stuck.
This does not affect the behavior on larger screens. Only small ones, where the sidebar covers up the main content.

rustdoc: use a more compact encoding for implementors/trait.*.js
The exact amount that this reduces the size of an implementors file depends on whether most of the impls are synthetic or not. For `Send`, it reduces the file from 128K to 112K, while for `Clone` it went from 64K to 44K.
