Improve rustdoc JS tests error output
It's pretty common when starting to add new tests for rustdoc-js to have issues to understand the errors. With this, it should make things a bit simpler. So now, in case of an error, it displays:
```
---- [js-doc-test] rustdoc-js/basic.rs stdout ----
error: rustdoc-js test failed!
failed to decode compiler output as json: line: {
output: Checking "basic" ... FAILED
==> Result not found in 'others': '{"path":"basic","name":"Fo"}'
Diff of first error:
{
"path": "basic",
- "name": "Fo",
+ "name": "Foo",
}
thread '[js-doc-test] rustdoc-js/basic.rs' panicked at 'explicit panic', src/tools/compiletest/src/json.rs:126:21
```
I think it was ``@camelid`` who asked about it a few days ago?

BTreeMap: try to enhance various comments
All in internal documentation, propagating the "key-value pair" notation from public documentation.

Rename "stability" CSS class to "item-info" and combine `document_stability` with `document_short`
Follow-up of #79300
The point of this PR is to make the CSS class more accurate since it's not only about stability anymore.

Require allocator to be static for boxed `Pin`-API
Allocators has to retain their validity until the instance and all of its clones are dropped. When pinning a value, it must live forever, thus, the allocator requires a `'static` lifetime for pinning a value. [Example from reddit](https://www.reddit.com/r/rust/comments/jymzdw/the_story_continues_vec_now_supports_custom/gd7qak2?utm_source=share&utm_medium=web2x&context=3):
```rust
let alloc = MyAlloc(/* ... */);
let pinned = Box::pin_in(42, alloc);
mem::forget(pinned); // Now `value` must live forever
// Otherwise `Pin`'s invariants are violated, storage invalidated
// before Drop was called.
// borrow of `memory` can end here, there is no value keeping it.
drop(alloc); // Oh, value doesn't live forever.
```
Sync rustc_codegen_cranelift
This implements a few extra simd intrinsics, fixes yet another 128bit bug and updates a few dependencies. It also fixes an cg_clif subtree update that did compile, but that caused a panic when compiling libcore. Other than that this is mostly cleanups.

Convert UNC path to local path to satisfy install script on Windows
`mkdir` with the `-p` flag attempts to create `//?` if passed a UNC path. This fails on both MSYS2 and Git Bash.
The UNC paths come from [canonicalizing](32da90b431/src/bootstrap/install.rs (L79)) the install prefix path. `mkdir -p` gets invoked on the [install script](d66f476b4d/install-template.sh (L149)).
Resolve typedefs in HashMap gdb/lldb pretty-printers
`GetTypedefedType` (LLDB) and `strip_typedefs` (GDB) calls are needed to resolve key and value types completely.
Without these calls, debugger doesn't show the actual type.
**Before** (without `GetTypedefedType`):
```
(lldb) frame variable hm[0]
(T) hm[0] = { ... }
```
**After** (with `GetTypedefedType`):
```
(lldb) frame variable hm[0]
((i32, alloc::string::String)) hm[0] = { ... }
```

rustc_parse: fix ConstBlock expr span
The span for a ConstBlock expression should presumably run through the end of the block it contains and not stop at the keyword, just like is done with similar block-containing expression kinds, such as a TryBlock
Properly handle attributes on statements
We now collect tokens for the underlying node wrapped by `StmtKind`
nstead of storing tokens directly in `Stmt`.
`LazyTokenStream` now supports capturing a trailing semicolon after it
is initially constructed. This allows us to avoid refactoring statement
parsing to wrap the parsing of the semicolon in `parse_tokens`.
Attributes on item statements
(e.g. `fn foo() { #[bar] struct MyStruct; }`) are now treated as
item attributes, not statement attributes, which is consistent with how
we handle attributes on other kinds of statements. The feature-gating
code is adjusted so that proc-macro attributes are still allowed on item
statements on stable.
Two built-in macros (`#[global_allocator]` and `#[test]`) needed to be
adjusted to support being passed `Annotatable::Stmt`.
Split match exhaustiveness into two files
I feel the constructor-related things in the `_match` module make enough sense on their own so I split them off. It makes `_match` feel less like a complicated mess. I'm not aware of PRs in progress against this module apart from my own so hopefully I'm not annoying too many people.
I have a lot of questions about the conventions in naming and modules around the compiler. Like, why is the module named `_match`? Could I rename it to `usefulness` maybe? Should `deconstruct_pat` be a submodule of `_match` since only `_match` uses it? Is it ok to move big piles of code around even if it makes git blame more difficult?

Cleanup more of rustdoc
- Use `Item::from_def_id` for StructField
- Use `from_def_id_and_parts` for primitives and keywords
- Take `String` instead of `Symbol` in `from_def_id` - this avoids having to intern then immediately stringify the existing string.
- Remove unused `get_stability` and `get_deprecation`
- Remove unused `attrs` field from `primitives`
- Remove unused `attrs` field from `keywords`
This will probably conflict with https://github.com/rust-lang/rust/pull/79335 and I would prefer for that PR to land first - I'm anxious for https://github.com/rust-lang/rust/pull/77467 to land :)
Makes https://github.com/rust-lang/rust/issues/76998 easier to add.

Add support for Arm64 Catalyst on ARM Macs
This is an iteration on https://github.com/rust-lang/rust/pull/63467 which was merged a while ago. In the aforementioned PR, I added support for the `X86_64-apple-ios-macabi` target triple, which is Catalyst, iOS apps running on macOS.
Very soon, Apple will launch ARM64 based Macs which will introduce `aarch64_apple_darwin.rs`, macOS apps using the Darwin ABI running on ARM. This PR adds support for Catalyst apps on ARM Macs: iOS apps compiled for the darwin ABI.
I don't have access to a Apple Developer Transition Kit (DTK), so I can't really test if the generated binaries work correctly. I'm vaguely hopeful that somebody with access to a DTK could give this a spin.
This preserves the current lint behavior for now.
Linting after item statements currently prevents the compiler from bootstrapping.
Fixing this is blocked on fixing this upstream in Cargo, and bumping the Cargo
submodule.
Loading a macro from libstd causes us to load serialized
`SyntaxContext`s in a platform-dependent way, causing the printed spans
to differ between platforms.
