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`.
For example, `1` is parsed as an integer literal, but it can be turned
into a float with the suffix `f32`. Now the error calls them "numeric
literals" and notes that you can add a float suffix since they can be
either integers or floats.
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?
