Before, rustdoc was missing `-C passes=list` and the "Available options"
header.
Making these match allows testing that they match exactly.

rustdoc: remove redundant expandSection code from main.js
This functionality is already tested in `hash-item-expansion.goml`, and was implemented twice:
* First, in code that ran at load time and at hash change: 917cdd295d2eed213c135d6f984c650f016ee3d6
* Later, the hash change event handler was itself run at load time, and the code handling both cases diverged in implementation, though their behavior still matches pretty well: f66a331335f3ac931afabca6f927a9d7dc17db3e

Initial support for loongarch64-unknown-linux-gnu
Hi, We hope to add a new port in rust for LoongArch.
LoongArch intro
LoongArch is a RISC style ISA which is independently designed by Loongson
Technology in China. It is divided into two versions, the 32-bit version (LA32)
and the 64-bit version (LA64). LA64 applications have application-level
backward binary compatibility with LA32 applications. LoongArch is composed of
a basic part (Loongson Base) and an expanded part. The expansion part includes
Loongson Binary Translation (LBT), Loongson VirtualiZation (LVZ), Loongson SIMD
EXtension (LSX) and Loongson Advanced SIMD EXtension(LASX).
Currently the LA464 processor core supports LoongArch ISA and the Loongson
3A5000 processor integrates 4 64-bit LA464 cores. LA464 is a four-issue 64-bit
high-performance processor core. It can be used as a single core for high-end
embedded and desktop applications, or as a basic processor core to form an
on-chip multi-core system for server and high-performance machine applications.
Documentations:
ISA:
https://loongson.github.io/LoongArch-Documentation/LoongArch-Vol1-EN.html
ABI:
https://loongson.github.io/LoongArch-Documentation/LoongArch-ELF-ABI-EN.html
More docs can be found at:
https://loongson.github.io/LoongArch-Documentation/README-EN.html
Since last year, we have locally adapted two versions of rust, rust1.41 and rust1.57, and completed the test locally.
I'm not sure if I'm submitting all the patches at once, so I split up the patches and here's one of the commits

rustc_metadata: Filter encoded data more aggressively using `DefKind`
I focused on data that contains spans, because spans are expensive to encode/decode/hash, but also touched `should_encode_visibility` too.
One incorrect use of impl visibility in diagnostics is also replaced with trait visibility.

resolve: Preserve reexport chains in `ModChild`ren
This may be potentially useful for
- avoiding uses of `hir::ItemKind::Use` (which usually lead to correctness issues)
- preserving documentation comments on all reexports, including those from other crates
- preserving and checking stability/deprecation info on reexports
- all kinds of diagnostics
The second commit then migrates some hacky logic from rustdoc to `module_reexports` to make it simpler and more correct.
Ideally rustdoc should use `module_reexports` immediately at the top level, so `hir::ItemKind::Use`s are never used.
The second commit also fixes issues with https://github.com/rust-lang/rust/pull/109330 and therefore

rustdoc: add test and bug fix for theme defaults

* Stop checking `func` in `onEach`. It's always hard-coded right
at the call site, so there's no point.
* Use the ternary operator in a few spots where it makes sense.
* No point in making `onEach` store `arr.length` in a variable if
it's only used once anyway.

write threads info into log only when debugging
The current tracing log will unconditionally write thread information during parallel compilation, which sometimes confuses some normal output log information
This fixes the UI test failure of:

Source code scrollbar
Fixes https://github.com/rust-lang/rust/issues/109865.
You can test it [here](https://rustdoc.crud.net/imperio/source-code-scrollbar/src/test_docs/lib.rs.html).
It seems to introduce a few regressions (at least change of behaviour) about the scroll "saving" though.

Don't collect return-position impl traits for documentation
#104889 modified the rustdoc ast collection step to use a HIR visitor, which more thoroughly walks the HIR tree. that means that we're going to encounter inner items (incl return-position impl traits and async fn opaque futures) that are not possible to document.
FIxes (but does not close due to being a beta regression) #109931

rustdoc: escape GAT args in more cases
Fixes #109488.
Previously we printed the *un*escaped form of GAT arguments not only when `f.alternate()` was true but *also* when we failed to compute the URL of the trait associated with the type projection, i.e. when `href(…)` returned an `Err(_)`.
In this PR the argument printing logic is entirely separate from the link resolution code above as it should be.
Further, we now only try to compute the URL if the HTML format was requested with `!f.alternate()`. Before, we would sometimes compute the `href` only to throw it away later.

rustdoc: make intra-doc link pass non-quadratic for repeated links
In the collect_intra_doc_links pass, links to a given item that occurred repeatedly were getting inserted into a `Vec<clean::ItemLink>` repeatedly. This led to n^2 behavior (where n = the number of pages generated), particularly for the intra-doc link on the `Into<U> for T where U: From<T>` blanket implementation, since that link appears on every single struct page.

Move `doc(primitive)` future incompat warning to `invalid_doc_attributes`
Fixes #88070.
It's been a while since this was turned into a "future incompatible lint" so I think we can now turn it into a hard error without problem.

rustdoc: Fix invalid suggestions on ambiguous intra doc links v2
Fixes https://github.com/rust-lang/rust/issues/108653.
This is another approach to fixing the same issue. This time, we keep the computed information around instead of re-computing it.
Strangely enough, the order for ambiguities seem to have been changed. Not an issue but it creates a lot of diff...
So which version do you prefer?

Initial support for return type notation (RTN)
See: https://smallcultfollowing.com/babysteps/blog/2023/02/13/return-type-notation-send-bounds-part-2/
1. Only supports `T: Trait<method(): Send>` style bounds, not `<T as Trait>::method(): Send`. Checking validity and injecting an implicit binder for all of the late-bound method generics is harder to do for the latter.
* I'd add this in a follow-up.
3. ~Doesn't support RTN in general type position, i.e. no `let x: <T as Trait>::method() = ...`~
* I don't think we actually want this.
5. Doesn't add syntax for "eliding" the function args -- i.e. for now, we write `method(): Send` instead of `method(..): Send`.
* May be a hazard if we try to add it in the future. I'll probably add it in a follow-up later, with a structured suggestion to change `method()` to `method(..)` once we add it.
7. ~I'm not in love with the feature gate name 😺~
* I renamed it to `return_type_notation` :heavy_check_mark:
Follow-up PRs will probably add support for `where T::method(): Send` bounds. I'm not sure if we ever want to support return-type-notation in arbitrary type positions. I may also make the bounds require `..` in the args list later.

Partial stabilization of `once_cell`
This PR aims to stabilize a portion of the `once_cell` feature:
- `core::cell::OnceCell`
- `std::cell::OnceCell` (re-export of the above)
- `std::sync::OnceLock`
This will leave `LazyCell` and `LazyLock` unstabilized, which have been moved to the `lazy_cell` feature flag.
Tracking issue: https://github.com/rust-lang/rust/issues/74465 (does not fully close, but it may make sense to move to a new issue)
Future steps for separate PRs:
- ~~Add `#[inline]` to many methods~~ #105651
- Update cranelift usage of the `once_cell` crate
- Update rust-analyzer usage of the `once_cell` crate
- Update error messages discussing once_cell
## To be stabilized API summary
```rust
// core::cell (in core/cell/once.rs)
pub struct OnceCell<T> { .. }
impl<T> OnceCell<T> {
pub const fn new() -> OnceCell<T>;
pub fn get(&self) -> Option<&T>;
pub fn get_mut(&mut self) -> Option<&mut T>;
pub fn set(&self, value: T) -> Result<(), T>;
pub fn get_or_init<F>(&self, f: F) -> &T where F: FnOnce() -> T;
pub fn into_inner(self) -> Option<T>;
pub fn take(&mut self) -> Option<T>;
}

impl<T: Debug> Debug for OnceCell<T>
impl<T> Default for OnceCell<T>;
impl<T> From<T> for OnceCell<T>;

```rust

unsafe impl<T: Send> Send for OnceLock<T>;
unsafe impl<T: Sync + Send> Sync for OnceLock<T>;
impl<T: UnwindSafe> UnwindSafe for OnceLock<T>;
```
No longer planned as part of this PR, and moved to the `rust_cell_try` feature gate:
```rust
impl<T> OnceCell<T> {
pub fn get_or_try_init<F, E>(&self, f: F) -> Result<&T, E> where F: FnOnce() -> Result<T, E>;
}
impl<T> OnceLock<T> {
pub fn get_or_try_init<F, E>(&self, f: F) -> Result<&T, E> where F: FnOnce() -> Result<T, E>;
}
```
I am new to this process so would appreciate mentorship wherever needed.
