Create VecDeque directly from the array instead of inserting items one-by-one.
As suggested in rust-lang#88564. This adds a `try_clone()` to `OwnedFd` by
refactoring the code out of the existing `File`/`Socket` code.
Changes doc text to refer to the "default" parameter as the "default"
function.

Enable outline-atomics by default as enabled in clang by the following commit
https://reviews.llvm.org/rGc5e7e649d537067dec7111f3de1430d0fc8a4d11

Performance improves by several orders of magnitude when using the LSE instructions
instead of the ARMv8.0 compatible load/store exclusive instructions.

Tested on Graviton2 aarch64-linux with
x.py build && x.py install && x.py test
This change makes it consistent with `Hash` for all other collections.
A subset of places referred to 'super-trait', so this changes them
to all use 'supertrait'. This matches 'supertype' and some other
usages. An exception is 'auto-trait' which is consistently used
in that manner.

implement advance_(back_)_by on more iterators

Add more efficient, non-default implementations for `feature(iter_advance_by)` (rust-lang#77404) on more iterators and adapters.

This PR only contains implementations where skipping over items doesn't elide any observable side-effects such as user-provided closures or `clone()` functions. I'll put those in a separate PR.
Fix an ICE caused by type mismatch errors being ignored

This PR fixes rust-lang#87771. It turns out that the check on `compiler/rustc_typeck/src/check/demand.rs:148` leads to the ICE. I removed it because the early return in [`check_expr_assign`](https://github.com/theo-lw/rust/blob/dec7fc3ced5bc3c18d0e5d29921d087f93189cb8/compiler/rustc_typeck/src/check/expr.rs#L928) already prevents unnecessary error messages from the call to `check_expr_coercable_to_type`.

VecDeque: improve performance for From<[T; N]>

Create `VecDeque` directly from the array instead of inserting items one-by-one.

Benchmark
```
./x.py bench library/alloc --test-args vec_deque::bench_from_array_1000
```

* Before
```
test vec_deque::bench_from_array_1000                    ... bench:       3,991 ns/iter (+/- 717)
```

* After
```
test vec_deque::bench_from_array_1000                    ... bench:         268 ns/iter (+/- 37)
```

Improve wording of `map_or_else` docs

Changes doc text to refer to the "default" parameter as the "default"
function.

Previously, the doc text referred to the "f" parameter as the "default" function; and the "default" parameter as the "fallback" function.

Recommend running `cargo clean` in E0514 output

This suggestion has worked for me before. Seems to me it could help others.

Consistently use 'supertrait'.

to all use 'supertrait'. This matches 'supertype' and some other

Fix ICE with buffered lint referring to AST node deleted by everybody_loops

Fixes rust-lang#87308. Note the following comment:
https://github.com/rust-lang/rust/blob/08759c691e2e9799a3c6780ffdf910240ebd4a6b/compiler/rustc_lint/src/early.rs#L415-L417

As it turns out, this is not _always_ a bug, because `-Zunpretty=everybody_loops` causes a lot of AST nodes to be deleted, and thus some buffered lints will refer to non-existent node ids. To fix this, my changes simply ignore buffered lints if `-Zunpretty=everybody_loops` is enabled, which, from my understanding, shouldn't be a big issue because it only affects pretty-printing. Of course, a more elegant solution would only ignore buffered lints that actually point at deleted node ids, but I haven't figured out an easy way of achieving this.

For the concrete example in rust-lang#87308, the buffered lint is created [here](https://github.com/rust-lang/rust/blob/08759c691e2e9799a3c6780ffdf910240ebd4a6b/compiler/rustc_expand/src/mbe/macro_rules.rs#L145-L151) with the `lint_node_id` from [here](https://github.com/rust-lang/rust/blob/08759c691e2e9799a3c6780ffdf910240ebd4a6b/compiler/rustc_expand/src/mbe/macro_rules.rs#L319), i.e. it points at the macro _expansion_, which then gets deleted by `ReplaceBodyWithLoop` [here](https://github.com/rust-lang/rust/blob/08759c691e2e9799a3c6780ffdf910240ebd4a6b/compiler/rustc_interface/src/passes.rs#L377).

The queue's really big, going to try and get some rollups in. Feel free to give some of the rollup=never PRs higher priority if necessary, or reopen the tree if I end up not being super responsive (you can ping me on Zulip or Discord).
