5a872880bd Auto merge of #29780 - KyleMayes:quote-ext, r=nrc
This is my first code contribution to Rust, so I'm sure there are some issues with the changes I've made.

I've added the `quote_arg!`, `quote_block!`, `quote_path!`, and `quote_meta_item!` quasiquoting macros. From my experience trying to build AST in compiler plugins, I would like to be able to build any AST piece with a quasiquoting macro (e.g., `quote_struct_field!` or `quote_variant!`) and then use those AST pieces in other quasiquoting macros, but this pull request just adds some of the low-hanging fruit.

I'm not sure if these additions are desirable, and I'm sure these macros can be implemented in an external crate if not.

For now, this pass does some easy transformations, like eliminating
empty blocks that just jump to another block, some trivial
conversion of If terminators into Gotos and removal of dead blocks.

8c9c9513cf Auto merge of #29544 - Ryman:reduce_doc_warnings, r=steveklabnik
Did this alphabetically, so I didn't see [how `std` was doing things](https://dxr.mozilla.org/rust/source/src/libstd/lib.rs#215) till I was nearly finished. If you prefer to add crate-level-whitelists like std instead of test-level, I can rebase with that strategy.

A number of these commits can probably be dropped as the crates don't have much to test, and are deprecated. Let me know which if any to drop! (can also squash after review if desired)

0bd708461b Auto merge of #29770 - ollie27:assert_eq_unsized, r=alexcrichton
`format_args!` doesn't support none Sized types so we should just pass it the references to `left_val` and `right_val`.

The following works:
```rust
assert!([1, 2, 3][..] == vec![1, 2, 3][..])
```
So I would expect this to as well:
```rust
assert_eq!([1, 2, 3][..], vec![1, 2, 3][..])
```
But it fails with "error: the trait `core::marker::Sized` is not implemented for the type `[_]` [E0277]"
I don't know if this change will have any nasty side effects I don't understand.

0b510641d3 Improve the detailed error message for E0432
The command-line error message for E0432 does mention the possibility of
missing the `extern crate` declaration, but the detailed error message
for it doesn't.

Fixes #29517.

Fix usage of wrong article in `Result` docs.

This is my first rust PR, if something about the process is wrong let me know.

This mostly brings them in line with existing linking convention, but
also has some minor re-wording.

The text at the top has been re-focused, by starting out with what the
prelude does, rather than starting from injecting std.

Also, it now mentions that other preludes exist.

b7f6d7239b Rollup merge of #29776 - nikomatsakis:mir-29740, r=nrc
In previous PRs, I changed the match desugaring to generate more efficient code for ints/chars and the like. But this doesn't help when you're matching strings, ranges, or other crazy complex things (leading to #29740). This commit restructures match desugaring *yet again* to handle that case better -- basically we now degenerate to an if-else-if chain in such cases.

~~Note that this builds on https://github.com/rust-lang/rust/pull/29763 which will hopefully land soon. So ignore the first few commits.~~ landed now

662232c8f6 Rewrite match algorithm to avoid massive blowup in generated code for
large matches that fallback to Eq. When we encounter a case where the
test being performed does not inform the candidate at all, we just stop
testing the candidates at that point, rather than adding the candidate
to both outcomes. The former behavior was not WRONG, but it generated a
lot of code, whereas this new behavior degenerates to an if-else-if
tree.

Fixes #29740.
