Cosmetic improvements to doc comments
This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase).
r? @steveklabnik
Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!

Fix span for closure return type when annotated.
Fixes #58053.
This PR adjusts the span used to label closure return types so that
if the user specifies the return type, i.e. `|_| -> X {}` instead of
`|_| {}`, we correctly highlight all of it and not just the last
character.

Ease the transition to requiring features by just warning if there's no feature list
while we could make this change (it's all unstable after all), there are crates.io crates that use the feature and that the compiler depends upon. We can instead roll out this feature while still supporting the old way.

Initial implementation of rustfixable unused_imports lint
This PR adds the initial implementation of rustfixable `unused_imports` lint. The implementation works, but rustfix is not able to apply all the suggestions until https://github.com/rust-lang/rust/issues/53934 is fixed. It also needs https://github.com/rust-lang/rust/pull/58296 to hide the suggested note since it's really useless.

Rollup merge of #58345 - RalfJung:2nd-filename, r=matthewjasper
When there are multiple filenames, print what got interpreted as filenames
I have written code that crafts command lines for rustc, and when I get "multiple input filenames provided" it can be quite hard to figure out where in this long list of arguments the mistake is hiding. Probably I passed an argument to a flag that does not expect an argument, but which flag would that be?
This changes the error message to print the first two filenames, to make it easier to debug what is going on.

Use `to_ne_bytes` for converting IPv4Addr to octets
It is easier and it should be also faster, because [`to_ne_bytes`](https://doc.rust-lang.org/std/primitive.u32.html#method.to_ne_bytes) just calls `mem::transmute`.

This is useful for queries which produce results which are very likely to change if their inputs do.
I also expect this to be useful for end to end queries because 1) we don't need `HashStable` impls and 2) we avoid the overhead of hashing the result of large results like the AST or the HIR map.

Make `intern_lazy_const` actually intern its argument.
Currently it just unconditionally allocates it in the arena.
For a "Clean Check" build of the the `packed-simd` benchmark, this
change reduces both the `max-rss` and `faults` counts by 59%; it
slightly (~3%) increases the instruction counts but the `wall-time` is
unchanged.
For the same builds of a few other benchmarks, `max-rss` and `faults`
drop by 1--5%, but instruction counts and `wall-time` changes are in the
noise.
