This builder is not really the correct place to put this, but it
definitely has the time budget and checking this tool builds on just one
platform is more than sufficient.
Update Cargo submodule and its dependencies
Hopefully just another routine update!
So far this starts to enable the `std::arch` in stage0 builds of rustc.
This means that we may need stage0/not(stage0) in stdsimd itself, but
more and more code is starting to use `std::arch` so I think it's time
to start shifting the balance of work here.
This commit improves the calculation of code spans for intra-doc
resolution failures. All sugared doc comments should now have the
correct spans, including those where the comment is longer than the
docs.
It also fixes an issue where the spans were calculated incorrectly for
certain unsugared doc comments. The diagnostic will now always use the
span of the attributes, as originally intended.
Fixes#55964.

Add regression test for ICE
Fixes#55846 with a minimal (or as best as I can manage) test case. I tested this against 1.30.0 manually to confirm it crashes.
The issue seemed to have something to do with associated types. It's possible someone with more knowledge can shrink the test case down further, or make it clearer.
Remove `tokenstream::Delimited`.
Because it's an extra type layer that doesn't really help; in a couple
of places it actively gets in the way, and overall removing it makes the
code nicer. It does, however, move `tokenstream::TokenTree` further away
from the `TokenTree` in `quote.rs`.
More importantly, this change reduces the size of `TokenStream` from 48
bytes to 40 bytes on x86-64, which is enough to slightly reduce
instruction counts on numerous benchmarks, the best by 1.5%.
Note that `open_tt` and `close_tt` have gone from being methods on
`Delimited` to associated methods of `TokenTree`.

This commit also fixes up lifetimes a bit:
- Renames `'a` as `'p` when used with `Matrix` and `Pattern`, for
consistency.
- Removes some unnecessary `'p` lifetimes on some function arguments.
- Adds some missing lifetime parameters.
slice: tweak concat & join
- use `sum` instead of `fold` (readability)
- adjust the capacity for `join` - the number of separators is `n - 1`, not `n`; proof:
```
fn main() {
let a = [[1, 2], [4, 5]];
let v = a.join(&3);
assert_ne!(v.len(), v.capacity()); // len is 5, capacity is 6
}
```
