Fix invalid rules in .gitignore
`**node_modules` in a .gitignore is the same than
`*node_modules` or `*****node_modules`.
It matches every file whose name ends with `node_modules`,
including `not_node_modules`.
The intent here was obviously to have `**/node_modules`
which is the same than just `node_modules`.

Fix: non_exhaustive_omitted_patterns by filtering unstable and doc hidden variants
Fixes: #89042
Now that #86809 has been merged there are cases (std::io::ErrorKind) where unstable feature gated variants were included in warning/error messages when the feature was not turned on. This filters those variants out of the return of `SplitWildcard::new`.
Variants marked `doc(hidden)` are filtered out of the witnesses list in `Usefulness::apply_constructor`.
Probably worth a perf run 🤷 since this area can be sensitive.

fix minor spelling error in Poll::ready docs
Fixes minor spelling error in the proposed `Poll::ready` docs. Not that my opinion matters, but +1 on the original PR (#89651), it reads much nicer to me than the `ready!` macro.
Add #[must_use] to is_condition tests
I threw in `std::path::Path::has_root` for funsies.
A continuation of #89718.

Add #[must_use] to non-mutating verb methods
These are methods that could be misconstrued to mutate their input, similar to #89694. I gave each one a different custom message.
I wrote that `upgrade` and `downgrade` don't modify the input pointers. Logically they don't, but technically they do...

Remove built-in query cache_hit tracking
This was already only enabled in debug_assertions builds. Generally, it seems
like most use cases that would use this could also use the -Zself-profile flag
which also tracks cache hits (in all builds), and so the extra cfg's and such
are not really necessary.
This is largely just a small cleanup though, which primarily is intended to make
other changes easier by avoiding the need to deal with this field.
Add test cases for unstable variants
Add test cases for doc hidden variants
Move is_doc_hidden to method on TyCtxt
Add unstable variants test to reachable-patterns ui test
Rename reachable-patterns -> omitted-patterns
Add #[must_use] to From::from and Into::into

The 128 bit case remains ridiculously slow because llvm fails to optimize division by a constant 128-bit value to multiplications. This could be worked around but it seems preferable to fix this in llvm.
From u32 up, table lookup (like suggested [here](https://github.com/rust-lang/rust/issues/70887#issuecomment-881099813)) is still faster, but requires a hardware `leading_zeros` to be viable, and might clog up the cache.
Fix ICE when compiling nightly std/rustc on beta compiler
Fix#89775#89479 renames a lot of diagnostic items, but it happens that the beta compiler assumes that there must be DefId with `rustc_diagnostic_item = "send_trait"`, causing an ICE when compiling stage 0 std or stage 1 compiler. So gate it with `cfg(bootstrap)`.
The unwrap is also removed, so that existence of the diagnostic item is not required. I ripgreped the code base and this seems the only place where `unwrap` is called on the return value of `get_diagnostic_item`.
Fix function-names test for GDB 10.1
This PR updates the test output in `src/test/debuginfo/function-names.rs` for GDB 10.1.
This should fix issue https://github.com/rust-lang/rust/issues/89750 -- but not the underlying problem of CI ignoring tests if not viable debugger happens to be present.
