Use variant names rather than descriptions for identifying desugarings in `#[rustc_on_unimplemented]`.
Both are highly unstable, but variant name is at least a single identifier.

Rollup merge of #60458 - KodrAus:debug_map_entry, r=alexcrichton 
Add key and value methods to DebugMap

Implementation PR for an active (not approved) RFC: https://github.com/rust-lang/rfcs/pull/2696.

Add two new methods to `std::fmt::DebugMap` for writing the key and value part of a map entry separately:

```rust
impl<'a, 'b: 'a> DebugMap<'a, 'b> {
    pub fn key(&mut self, key: &dyn Debug) -> &mut Self;
    pub fn value(&mut self, value: &dyn Debug) -> &mut Self;
}
```

I want to do this so that I can write a `serde::Serializer` that forwards to our format builders, so that any `T: Serialize` can also be treated like a `T: Debug`.

5748825cc8 Auto merge of #61682 - Centril:stabilize-type_alias_enum_variants, r=petrochenkov 
Stabilize `type_alias_enum_variants` in Rust 1.37.0

Stabilize `#![feature(type_alias_enum_variants)]` which allows type-relative resolution with highest priority to `enum` variants in both expression and pattern contexts. For example, you may now write:

```rust
enum Option<T> {
    None,
    Some(T),
}

type OptAlias<T> = Option<T>;

fn work_on_alias(x: Option<u8>) -> u8 {
    match x {
        OptAlias::Some(y) => y + 1,
        OptAlias::None => 0,
    }
}
```

61a60ce7d3 Auto merge of #61229 - Centril:stabilize-repr_align_enum, r=nagisa 
Stabilize #![feature(repr_align_enum)] in Rust 1.37.0

On an `enum` item, you may now write:

```rust
#[repr(align(X))]
enum Foo {
    // ...
}
```

This has equivalent effects to first defining:

```rust
#[repr(align(X))]
struct AlignX<T>(T);
```

and then using `AlignX<Foo>` in `Foo`'s stead.

Rollup merge of #59747 - gruberb:copy-book-toml-unstable-book, r=ehuss 
Copy book.toml unstable book generator

Solves https://github.com/rust-lang/rust/issues/59554 and adds a book title to the unstable book.

I assume that [copy_recursive](acd8dd6a50/src/tools/unstable-book-gen/src/main.rs (L105)) will take files regardless of their type (`.md` or `.toml`).

Although I had a hard time time testing it. A second pair of eyes is definitely needed.

850912704e Auto merge of #59211 - nox:refcell-borrow-state, r=KodrAus 
Introduce RefCell::try_borrow_unguarded

*Come sit next to the fireplace with me, this is going to be a long story.*

So, you may already be aware that Servo has weird design constraints that forces us developers working on it to do weird things. The thing that interests us today is that we do layout on a separate thread with its own thread pool to do some things in parallel, whereas the data it uses comes from the script thread, which implements the entire DOM and related pieces, with `!Sync` data types such as `RefCell<T>`.

The invariant we maintain is that script does not do anything ever with the DOM data as long as layout is doing its job. That's all nice and all, but one thing we don't ensure is that we don't actually know if script was currently mutably borrowing some `RefCell<T>` prior to starting layout, which may lead to aliasing mutable memory and obviously undefined behaviour.

This PR reinstates `RefCell::borrow_state` so that [this method](https://github.com/servo/servo/blob/master/components/script/dom/bindings/cell.rs#L23-L30) can make use of it and return `None` if the cell was mutably borrowed.
