get rid of NoMirFor error variant
The only place where we throw that error, it is very quickly caught again and turned into a different error. So raise that other error immediately.
Update VxWork's UNIX support
1. VxWorks does not provide glibc
2. VxWorks does provide `sigemptyset` and `sigaddset`
Note: these changes are concurrent to [this PR](https://github.com/rust-lang/libc/pull/2295) in libc.
Add flag to configure `large_assignments` lint
The `large_assignments` lints detects moves over specified limit. The
limit is configured through `move_size_limit = "N"` attribute placed at
the root of a crate. When attribute is absent, the lint is disabled.
Make it possible to enable the lint without making any changes to the
source code, through a new flag `-Zmove-size-limit=N`. For example, to
detect moves exceeding 1023 bytes in a cargo crate, including all
dependencies one could use:
```
$ env RUSTFLAGS=-Zmove-size-limit=1024 cargo build -vv
```
Lint tracking issue #83518.
implement fold() on array::IntoIter to improve flatten().collect() perf
With #87168 flattening `array::IntoIter`s is now `TrustedLen`, the `FromIterator` implementation for `Vec` has a specialization for `TrustedLen` iterators which uses internal iteration. This implements one of the main internal iteration methods on `array::Into` to optimize the combination of those two features.
This should address the main issue in #87411
```
# old
test vec::bench_flat_map_collect ... bench: 2,244,024 ns/iter (+/- 18,903)
# new
test vec::bench_flat_map_collect ... bench: 172,863 ns/iter (+/- 2,141)
```
As proposed in the pull request thread, there is some inconsistency in
handling the `--no-deps` flag which requires `--` before it, and
`--fix` flag which does not.
In this commit the `--no-deps` flag does not need the `--` anymore.
However, it can still be used that way: `cargo clipyy -- --no-deps`.
Use diagnostic items where possible
Clippy still uses a bunch of paths in places that could easily use already defined diagnostic items. This PR updates all references to such paths and also removes a bunch of them that are no longer needed after this cleanup.
Some paths are also used to construct new paths and can therefore not be removed that easily. I've added a doc comment to those instances that recommends the use of the diagnostic item where possible.
And that's it, cleaning crew signing off 🧹🗑️

Remove unstable `--pretty` flag
It doesn't do anything `--unpretty` doesn't, and due to a bug, also
didn't show up in `--help`. I don't think there's any reason to keep it
around, I haven't seen anyone using it.
Closes https://github.com/rust-lang/rust/issues/36473.
Make StrSearcher behave correctly on empty needle
Fix#85462.
This will not affect ABI since the other variant of the enum is bigger.
It may break some code, but that would be very strange: usually people
don't continue after the first `Done` (or `None` for a normal iterator).

`--no-deps` filled in with a little more information. Explain that
`--fix` implies `--no-deps`.
Explain that `--no-deps` is used with `cargo clippy --`, including
one example.
Add missing whitespace after attribute in HTML template
Firefox (even though it worked) highlights it as red when you look at the source code because there is a missing whitespace.

Remove unnecessary `structhead` parameter from `render_union`
`structhead` is used for `render_struct` so that the logic for rendering
structs can be shared between struct variants and struct items. However,
`render_union` is not used anywhere except for rendering union items, so
its `structhead` parameter is unnecessary.
