Use ControlFlow in more places
Now, instead of manually using variables in visitors to signify that a visit is "done" and that the visitor should stop traversing. We use the trait type "Result" to signify this (in relevant places).
I'll schedule a perf run, I don't think it will be much of a difference, but every bit of performance is welcomed :)
changelog: Improve performance, less memory use in visitors
Fixes#12829
r? `@y21`
Make ast `MutVisitor` have the same method name and style as `Visitor`
It doesn't map 100% because some `MutVisitor` methods can filter or even expand to multiple items, but consistency seems nicer.

Fix running compile-test under cargo nextest
`ui_test` itself has `cargo nextest` support which we now use - https://github.com/oli-obk/ui_test/pull/161
It prints `ui_test` as its test name whereas we printed `compile_test`, this ended up being treated as a test name filter causing all the tests to be filtered out

Temporarily remove myself from reviewer rotation
I'm going to focus on the project goal and my own contributions, this + medical stuff leaves me not enough time to review.
I'll still review any performance related PR, and you can still request from me a benchmark for a PR, and will finish the PRs that I'm still assign to.

Misc refactorings
Various small re-orderings to check the HIR tree or AST before doing other checks. Also includes a small bug fix for `arc_with_small_send_sync` not actually checking for `Arc::new`.

Misc refactorings part 5
`toplevel_ref_arg` gets a small fix so it can be allowed on function arguments. Otherwise just some rearrangements.

add lint for recreation of an entire struct
This lint makes Clippy warn about situations where an owned struct is
essentially recreated by moving all its fields into a new instance of
the struct. The lint is not machine-applicable because the source
struct may have been partially moved.
This lint originated in something I spotted during peer review. While
working on their branch a colleague ended up with a commit where a
function returned a struct that 1:1 replicated one of its owned inputs
from its members. Initially I suspected they hadn’t run their code
through Clippy but AFAICS there is no lint for this situation yet.
changelog: new lint: [`redundant_owned_struct_recreation`]
### New lint checklist
- \[+] Followed [lint naming conventions][lint_naming]
- \[+] Added passing UI tests (including committed `.stderr` file)
- \[+] `cargo test` passes locally
- \[+] Executed `cargo dev update_lints`
- \[+] Added lint documentation
- \[+] Run `cargo dev fmt`
Remove unnecessary impl sorting in queries and metadata
Removes unnecessary impl sorting because queries already return their keys in HIR definition order: https://github.com/rust-lang/rust/issues/120371#issuecomment-1926422838

changelog: [`pathbuf_init_then_push`]: new lint: Checks for calls to `push` immediately after creating a new `PathBuf`
Just a mirror of VEC_INIT_THEN_PUSH
Clean up a few minor refs in `format!` macro, as it has a performance cost. Apparently the compiler is unable to inline `format!("{}", &variable)`, and does a run-time double-reference instead (format macro already does one level referencing).
Inlining format args prevents accidental `&` misuse.
Lintcheck: Update crates and expand CI testset to 200 crates
This PR adds a new `ci_crates.toml` to lintcheck for our CI. The 200 crates take about 14 minutes, which is slightly more than the 10 I aimed for but still reasonable. The testset is constructed from:
* 5 crates that compile to binaries
* 4 crates that have been mentioned in ICE issues
* 1 crates "random" crates from `lintcheck_crates.toml`
* 190 crates from the top 200 crates from crates.io
During testing, I noticed a few panics in lintcheck. I've fixed them where possible, or at least improved the error message.
The new test set generates 500+ MB of json lints, which are compressed to a ~24mb artifact.
---
This PR also updates our `lintcheck_crates.toml`. I mainly updated the versions, removed some very outdated crates, and added some new ones. I targeted 25 crates as those are pretty fast to lint and a good precursor for our CI.
---
Optional TODO:
* It's likely that some crates are compiled several times. We could potentially safe some time, by using `--recursive` in our CI.
This is something I want to investigate, but it shouldn't be a blocker for this PR.
