Rollup merge of #59899 - nnethercote:sort-enum-variants-by-size, r=pnkfelix
In `-Zprint-type-size` output, sort enum variants by size.

It's useful to see the biggest variants first.

Rollup merge of #59852 - alexcrichton:more-vectored, r=sfackler
std: Add `{read,write}_vectored` for more types

This commit implements the `{read,write}_vectored` methods on more types
in the standard library, namely:

* `std::fs::File`
* `std::process::ChildStd{in,out,err}`
* `std::io::Std{in,out,err}`
* `std::io::Std{in,out,err}Lock`
* `std::io::Std{in,out,err}Raw`

Where supported the OS implementations hook up to native support,
otherwise it falls back to the already-defaulted implementation.

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.

Rollup merge of #59846 - euclio:not-a-module, r=davidtwco
clarify what the item is in "not a module" error

The motivation here was that I was trying to import an associated constant when I thought it was an enum variant, and got confused by this error.

Ideally I would like to add a note saying that associated constants, types, and methods cannot be imported, but I'm not sure that the associated items for a `Def` can be checked at resolve time.

Remove check_match from const_eval

This fixes #59378.

It seems that the `check_match` may be unnecessary, so this removes it per instructions provided in the issue. I re-ran the tests for `librustc_mir` and everything seemed fine!

9a612b2348 Auto merge of #59651 - tmandry:discr-index, r=eddyb
Add discr_index to multi-variant layouts

We remove the assumption that the discriminant is always field 0, in
preparations for layouts like generators where this is not (always) going to be
the case.

Specifically, upvars are going to go before the discriminant. In theory, it's possible to remove _that_ assumption instead and keep the discriminant at field index 0, but one assumption or the other had to go :)

There is one place I know of in the debuginfo code where we'll still need to remove assumptions that the discriminant is the _only_ field. I was planning on doing this along with the upcoming generator change, which will also include tests that exercise the code changing in this PR.

Rollup merge of #59894 - Xanewok:save-assoc-ty-qpath, r=eddyb
save-analysis: Pull associated type definition using `qpath_def`

Closes https://github.com/rust-lang/rls/issues/1390

This (probably?) fixes the case where we run the save-analysis code on the following snippet:
```rust
trait Test<'a> {
    type Thing: Test2;
}

trait Test2 {
    fn print();
}

#[allow(unused)]
fn example<T>(t: T)
    where T: for<'a> Test<'a>
{
    T::Thing::print(); //~ ERROR cannot extract an associated type from a higher-ranked trait bound in this context
    // ^ only errors in save-analysis mode
}
```

The chain is as follows:
- culprit is `hir_ty_to_ty`
- which calls `ast_ty_to_ty` in the `ItemCtxt`
- which calls `associated_path_to_ty`
- which finally fails on `projected_ty_from_poly_trait_ref`
3de0106789/src/librustc_typeck/collect.rs (L212-L224)

I'm not exactly sure why `hir_ty_to_ty` fails - is it because it needs more setup from typeck to work correctly? I'm guessing the fix is okay since we just pull the already typeck'd data (we run save-analysis after all the analysis passes are complete) from the tables.

With this change we can 'go to def' on all segments in the `T::Thing::print()` path.

Remove note about transmute for float bitpatterns.

This particular usecase has been safely abstracted in these `std` functions: [f32::to_bits](https://doc.rust-lang.org/std/primitive.f32.html#method.to_bits), [f32::from_bits](https://doc.rust-lang.org/std/primitive.f32.html#method.from_bits), [f64::to_bits](https://doc.rust-lang.org/std/primitive.f64.html#method.to_bits), [f64::from_bits](https://doc.rust-lang.org/std/primitive.f64.html#method.from_bits). So, I think we shouldn't recommend an unnecessary use of `unsafe` here anymore.
