Bump ui_test to 0.23
Notable changes: more control over run/rustfix/... and other rustc-specific features. All of these can in theory now be implemented entirely out of tree

Document never type fallback in `!`'s docs
Pulled the documentation I've written for #123939.
I want a single place where never type fallback is explained, which can be referred in all the lints and migration materials.
Changelog for Clippy 1.78 🪄
Roses and Violets have colors,
Red and Blue are the two,
I'm getting to the end of my masters,
what a cool goal to pursue

library/backtrace also declares a feature called `gimli-symbolize` which
appear used, but the feature in std with the same name is unused, so
remove it.
Add a lint against never type fallback affecting unsafe code
~~I'm not very happy with the code quality... `VecGraph` not allowing you to get predecessors is very annoying. This should work though, so there is that.~~ (ended up updating `VecGraph` to support getting predecessors)
~~First few commits are from https://github.com/rust-lang/rust/pull/123934https://github.com/rust-lang/rust/pull/123980~~
This is a workaround for #122758, but it's not clear why 1.79 requires a
more extensive amount of no_inline than the previous release. Seems like
there's something relatively subtle happening here.
Rewrite select (in the new solver) to use a `ProofTreeVisitor`
We can use a proof tree visitor rather than collecting and recomputing all the nested goals ourselves.
Based on #124415
There are a few tests that depend on some target features **not** being
enabled by default, and usually they are correct with the default x86-64
target CPU. However, in downstream builds we have modified the default
to fit our distros -- `x86-64-v2` in RHEL 9 and `x86-64-v3` in RHEL 10
-- and the latter especially trips tests that expect not to have AVX.
These cases are few enough that we can just set them back explicitly.
Arm bare-metal target doc changes
Updates the Arm bare-metal target docs:
* Detailed pages for all the Cortex-M targets, including details about setting target-cpu and target-features to suit specific Arm models
* More detail about the difference between `eabi` and `eabihf`
* Marks the Embedded Devices Working Group Cortex-M Team as the maintainer of the Cortex-M targets
rustc: document the jobserver
Explicitly document that the jobserver may be used by `rustc`, as well as recommend the `+` indicator for integration of `rustc` into GNU Make.
In particular, show the warning to increase the chances that this document is found when searching for solutions online.
In addition, add a note about the issue with GNU Make 4.3 since it is important that users realize they should do this even if they do not expect parallelism from `rustc`.
Finally, show how to workaround the issue of `$(shell ...)` calls in recursive Make (which e.g. was needed for the Linux kernel).
The GNU Make 4.4 case under `--jobserver-style=pipe` is not added since it got fixed after Rust 1.76.0 already (i.e. `rustc` will not warn if it finds the negative file descriptors).

v2: To be able to use tab characters for the Make examples, add `<!-- ignore-tidy-{check} -->` support to `tidy`.
v3: Added "Integration with build systems" section to hold the GNU Make one. Added "by clearing the `MAKEFLAGS` variable". Added "aforementioned" so that it is clear we are talking about the warning above.
v4: Added CMake subsection. Added a note that `rustc` may be affected by other flags, e.g. `CARGO_MAKEFLAGS`.
v5: Added that `rustc` will choose the number of jobs if a jobserver is not passed.
fix suggestion error for [`manual_is_ascii_check`] with missing type
fixes: #11324fixes: #11776
changelog: improve [`manual_is_ascii_check`] to suggest labeling type in closure, fix FP with type generics, and improve linting on ref expressions.
