Document `Item` type in `std::env::SplitPaths` iterator.
Previously there wasn't any documentation to show what the type of
`Item` was inside `std::env::SplitPaths`. Now, in the same format as
other examples of docs in `std` for `Iterator#Item`, we mention the
type.
This fixes#59543.

Reexport IntErrorKind in std
Currently `IntErrorKind` can only be found in `core`. @Centril confirmed on Discord that this is unintentional (should I r? him in this situation?).
Should there be a test for this? As far as this *specific* situation goes, I don't think so, I'll risk it and say that there's no way this regresses. However, it might be a good idea to have some tool detect public items in `core` that are not reexported in `std`. Does this belong in tidy, or should that be a separate tool? Is there some rustc-specific *linter*? Unless that's entirely a dumb idea, this should probably get an issue.
Note: My local build hasn't finished yet, but it's well past the point where I would expect problems.
Replace HashMap implementation with SwissTable (as an external crate)
This is the same as #56241 except that it imports `hashbrown` as an external crate instead of copying the implementation into libstd.
This includes a few API changes (all unstable):
- `try_reserve` is added to `HashSet`.
- Some trait bounds have been changed in the `raw_entry` API.
- `search_bucket` has been removed from the `raw_entry` API (doesn't work with SwissTable).
Disallow double trailing newlines in tidy
This wasn't done previously in https://github.com/rust-lang/rust/pull/47064#issuecomment-354533010 as it affected too many files, but I think it's best to fix it now so that the number of files with double trailing newlines doesn't keep increasing.

Fix sync_all on macos/ios
`sync_all` should flush all metadata in macos/ios, so it should call `fcntl` with the `F_FULLFSYNC` flag as `sync_data` does.
Note that without this `sync_data` performs more flushes than `sync_all` on macos/ios.
Remove collection-specific `with_capacity` documentation from `std::collections`
Fixes#59931
The style of `std::collections` module doc is very much a beginner friendly guide, and documenting niche, collection-specific behaviour feels out of place, if not brittle.
The note about `VecDeque` is outdated (see issue), and while `Vec` probably won't change its guarantees any time soon, the users who are interested in its allocation properties will find that in its own documentation.
Previously there wasn't any documentation to show what the type of
`Item` was inside `std::env::SplitPaths`. Now, in the same format as
other examples of docs in `srd` for `Iterator#Item`, we mention the
type.
This fixes#59543.
bump stdsimd; make intra_doc_link_resolution_failure an error again; make lints more consistent
I made `intra_doc_link_resolution_failure` warn so that it would properly respect `deny-warnings = false` in `config.toml`. `#[warn]` still become errors with `-D warnings` so I thought this was fine.
Turns out however that we don't pass `-D warnings` when running rustdoc, so for additional rustdoc-lints we need to set them to `deny`.
Also sue the opportunity to make the lint flags more consistent between libcore, liballoc, libstd.
Cc @gnzlbg for the *big* stdsimd update.
Make BufWriter use get_mut instead of manipulating inner in Write implementation
`get_mut` allows us to abstract over the implementation detail of inner being optional.
std: Add `{read,write}_vectored` for more types
This commit implements the `{read,write}_vectored` methods on more types
in the standard library, namely:
* `std::fs::File`
* `std::process::ChildStd{in,out,err}`
* `std::io::Std{in,out,err}`
* `std::io::Std{in,out,err}Lock`
* `std::io::Std{in,out,err}Raw`
Where supported the OS implementations hook up to native support,
otherwise it falls back to the already-defaulted implementation.
