add tests for some fixed ICEs

Fixes #55587.
Fixes #54348.

Looks like these ICEs are already fixed in nightly, so this PR just adds tests.

core/char: Speed up `to_digit()` for `radix <= 10`

I noticed that `char::to_digit()` seemed to do a bit of extra work for handling `[a-zA-Z]` characters. Since `to_digit(10)` seems to be the most common case (at least in the `rust` codebase) I thought it might be valuable to create a fast path for that case, and according to the benchmarks that I added in one of the commits it seems to pay off. I also created another fast path for the `radix < 10` case, which also seems to have a positive effect.

It is very well possible that I'm measuring something entirely unrelated though, so please verify these numbers and let me know if I missed something!

```

I ran the benchmark using:

```sh
python x.py bench src/libcore --stage 1 --keep-stage 0 --test-args "bench_to_digit"
```

A handful of hir tweaks

- remove an unused `hir_vec` macro pattern
- simplify `fmt::Debug` for `hir::Path` (take advantage of the `Display` implementation)
- remove an unused type alias (`CrateConfig`)
- simplify a `match` expression (join common patterns)

Change sidebar selector to fix compatibility with docs.rs

Fix for #55883.

fix various typos in doc comments

Unix RwLock: avoid racy access to write_locked

We should only access `write_locked` if we really got the lock.

Rewrite `...` as `..=` as a `MachineApplicable` 2018 idiom lint

Fixes https://github.com/rust-lang/rust/issues/51043.

Add mem::forget_unsized() for forgetting unsized values

~~Allows passing values of `T: ?Sized` types to `mem::drop` and `mem::forget`.~~

Adds `mem::forget_unsized()` that accepts `T: ?Sized`.

I had to revert the PR that removed the `forget` intrinsic and replaced it with `ManuallyDrop`: https://github.com/rust-lang/rust/pull/40559
We can't use `ManuallyDrop::new()` here because it needs `T: Sized` and we don't have support for unsized return values yet (will we ever?).
