Factor out several utils, add `path_def_id`
changelog: none
This is generally an effort to reduce the total number of utils. `path_def_id` is added which I believe is more "cross-cutting" and also complements `path_to_local`. Best reviewed one commit at a time.
Added:
* `path_def_id`
* `path_res`
Removed:
* `is_qpath_def_path`
* `match_any_diagnostic_items`
* `expr_path_res`
* `single_segment_path`
* `differing_macro_contexts`
* `is_ty_param_lang_item`
* `is_ty_param_diagnostic_item`
* `get_qpath_generics`
Renamed:
* `path_to_res` to `def_path_res`
* `get_qpath_generic_tys` to `qpath_generic_tys`
CC `@Jarcho` since this relates to some of your work and you may have input.
This was only used for the inclusion of 'current' dates into our manpages, but
it is not clear that this is practically necessary. The manpage is essentially
never updated, and so we can likely afford to keep a manual date in these files.
It also seems possible to just omit it, but that may cause other tools trouble,
so avoid doing that for now.
bootstrap: prefer using '--config' over 'RUST_BOOTSTRAP_CONFIG'

Rerun bootstrap's build script when RUSTC changes
Previously, rustbuild would give strange errors if you tried to reuse the same build directory under two names:
```
$ mkdir tmp && cd tmp
$ ../x.py check
Building rustbuild
Finished dev [unoptimized] target(s) in 35.27s
Checking stage0 std artifacts (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu)
^C
$ cd ..
$ mv tmp/build build
$ ./x.py check

Compiling bootstrap v0.0.0 (/home/jnelson/rust-lang/rust/src/bootstrap)
Finished dev [unoptimized] target(s) in 11.18s
failed to execute command: "/home/jnelson/rust-lang/rust/tmp/build/x86_64-unknown-linux-gnu/stage0/bin/rustc" "--target" "x86_64-unknown-linux-gnu" "--print" "target-libdir"
error: No such file or directory (os error 2)
```
This fixes the error. Reusing the same build directory is useful if you want to test path-related things in
bootstrap itself, without having to recompile it each time.
For good measure, this also reruns the build script when PATH changes.
Use shallow clones for submodules managed by rustbuild, not just bootstrap.py
I missed this in https://github.com/rust-lang/rust/pull/89757; it made
`x.py test src/bootstrap` very slow.
Update tracking issue for `const_fn_trait_bound`
It previously pointed to #57563, the conglomerate issue for `const fn` (presumably under the feature gate `const_fn`). This tracking issue doesn't mention anything about `const_fn_trait_bound`(the only occurrence of "trait bound" is for the now-removed `?const Trait` syntax), which can be confusing to people who want to find out more about trait bounds on `const fn`s. This pull request changes the tracking issue to one meant specifically for `const_fn_trait_bound`, #93706, which can help collect information on this feature's stabilization and point users towards `const_trait_impl` if they're looking for const-in-const-contexts trait bounds.
Fixes#93679.

Linkify sidebar headings for sibling items
Also adjust CSS so this doesn't produce excess padding/margin.
Note: I tried and failed to write a test with browser-UI-test. First I tried to `assert-property: (".block.mod h3 a", {"href": "index.html#macros"})`. But the `href` that gets read out is the fully-quallified URL, starting with `file:///`. That URL will differ depending on what path the test is run from, so that doesn't work.
Next I tried clicking on the appropriate sidebar link, and verifying that the appropriate heading on the next page is highlighted with the right background color. However, that also didn't work: according to browser-UI-test, the targeted heading was plain white. However, running with no-headless, I could see that it actually was yellow. I suspect this is a bug in the older version of Chromium used with browser-UI-test's bundled puppeteer, since it doesn't reproduce on latest Chrome.
Fixes#92957

Impl {Add,Sub,Mul,Div,Rem,BitXor,BitOr,BitAnd}Assign<$t> for Wrapping<$t> for rust 1.60.0
Tracking issue #93204
This is about adding basic integer operations to the `Wrapping` type:
```rust
let mut value = Wrapping(2u8);
value += 3u8;
value -= 1u8;
value *= 2u8;
value /= 2u8;
value %= 2u8;
value ^= 255u8;
value |= 123u8;
value &= 2u8;
```
Because this adds stable impls on a stable type, it runs into the following issue if an `#[unstable(...)]` attribute is used:
```
an `#[unstable]` annotation here has no effect
note: see issue #55436 <https://github.com/rust-lang/rust/issues/55436> for more information
```
This means - if I understood this correctly - the new impls have to be stabilized instantly.
Which in turn means, this PR has to kick of an FCP on the tracking issue as well?
This impl is analog to 1c0dc1810d#92356 for the `Saturating` type ``@dtolnay`` ``@Mark-Simulacrum``
Suggest 1-tuple parentheses on exprs without existing parens
A follow-on from #86116, split out from #90677.
This alters the suggestion to add a trailing comma to create a 1-tuple - previously we would only apply this if the relevant expression was parenthesised. We now make the suggestion regardless of parentheses, which reduces the fragility of the check (w.r.t formatting).
e.g.
```rust
let a: Option<(i32,)> = Some(3);
```
gets the below suggestion:
```rust
let a: Option<(i32,)> = Some((3,));
// ^ ^^
```
This change also improves the suggestion in other ways, such as by only making the suggestion if the types would match after the suggestion is applied and making the suggestion a multipart suggestion.
Make the pre-commit script pre-push instead
This should make it substantially less annoying, and hopefully more
people will find it useful. In particular, it will no longer run tidy
each time you run `git commit --amend` or rebase a branch.
This also warns if you have the old script in pre-commit; see the HACK
comment for details.

This adds in an enum when matching on positions which can either be types or consts.
It will default to emitting old special cased error messages for types.
use `fold_list` in `try_super_fold_with` for `SubstsRef`
split out from #93505 as this by itself is responsible for most of the perf improvements there

These statistics are computable from the self-profile data and/or ad-hoc
collectable as needed, and in the meantime contribute to rustc bootstrap times.
