This adds support for rust-lld for Apple *OS targets.
This was tested against targets "aarch64-apple-ios" and "aarch64-apple-ios-sim".
For targets "armv7-apple-ios" and "armv7s-apple-ios", it doesn't link because of
"symbols.o" not being generated with the correct CPU subtype (changes in
the "object" crate needs to be done to support it).
Add back Send and Sync impls on ChunksMut iterators
Fixes https://github.com/rust-lang/rust/issues/100014
These were accidentally removed in #94247 because the representation was changed from `&mut [T]` to `*mut T`, which has `!Send + !Sync`.

Fix futex module imports on wasm+atomics
The futex modules were rearranged a bit in #98707, which meant that wasm+atomics would no longer compile on nightly. I don’t believe any other targets were impacted by this.
do not claim that transmute is like memcpy
Saying transmute is like memcpy is not a well-formed statement, since memcpy is by-ref whereas transmute is by-val. The by-val nature of transmute inherently means that padding is lost along the way. (This is not specific to transmute, this is how all by-value operations work.) So adjust the docs to clarify this aspect.

Remove synchronization from Windows `hashmap_random_keys`
Unfortunately using synchronization when generating hashmap keys can prevent it being used in `DllMain`.

remove `commit_unconditionally`
`commit_unconditionally` is a noop unless we somehow inspect the current state of our snapshot. The only thing which does that is the leak check which was only used in one place where `commit_if_ok` is probably at least as, or even more, correct.
r? rust-lang/types
Improve position named arguments lint underline and formatting names
For named arguments used as implicit position arguments, underline both
the opening curly brace and either:
* if there is formatting, the next character (which will either be the
closing curl brace or the `:` denoting the start of formatting args)
* if there is no formatting, the entire arg span (important if there is
whitespace like `{ }`)
This should make it more obvious where the named argument should be.
Additionally, in the lint message, emit the formatting argument names
without a dollar sign to avoid potentially confusion.

parallelize HTML checking tool
there's a lot of IO, so timings on my laptop are far from stable, but it seems to be considerably faster.
this step often appears to take 5+ minutes in CI, so hopefully this offers a speedup
move [`assertions_on_result_states`] to restriction
"Backports" the first commit of https://github.com/rust-lang/rust-clippy/pull/9273, so that the lint doesn't go into beta as a warn-by-default lint.
The other changes in the linked PR can ride the train as usual.

RISC-V ASM test: relax label name constraint.
The test is currently [broken at LLVM Head](https://buildkite.com/llvm-project/rust-llvm-integrate-prototype/builds/12425#01825d5b-c3d1-4fdc-a98d-5956b246aee2), likely since 260a641068:

```
As far as I can tell, the exact index in the label probably doesn't matter for the test, especially if LLVM can change it to ~arbitrary values, though I'm not an ASM or RISC-V expert.
This [fixes the test](https://buildkite.com/llvm-project/rust-llvm-integrate-prototype/builds/12427).
Properly reject the `may_unwind` option in `global_asm!`
This was accidentally accepted even though it had no effect in
`global_asm!`. The option only makes sense for `asm!` which runs within
a function.
Remove Clean trait for ast::Attribute and improve Attributes::from_ast
I prefer to keep this commit on its own for this PR because I'm changing a bit more things than expected originally: I split `Attributes::from_ast` into two because there is only one location making use of its second parameter.
Follow-up of https://github.com/rust-lang/rust/pull/99638.
r? `@notriddle`
Always include a position span in `rustc_parse_format::Argument`
Moves the spans from the `Position` enum to always be included in the `Argument` struct. Doesn't make any changes to use it in rustc, but it will be useful for some upcoming Clippy lints
