Rollup merge of #68764 - Centril:self-semantic, r=petrochenkov 
parser: syntactically allow `self` in all `fn` contexts

Part of https://github.com/rust-lang/rust/pull/68728.

`self` parameters are now *syntactically* allowed as the first parameter irrespective of item context (and in function pointers). Instead, semantic validation (`ast_validation`) is used.

3c069a066e Change MIR building to fill in the resume place 
This changes `Yield` from `as_rvalue` to `into` lowering, which could
have a possible performance impact. I could imagine special-casing
some resume types here to use a simpler lowering for them, but it's
unclear if that makes sense at this stage.

Rollup merge of #68704 - jonas-schievink:ignore-build-fmt, r=Mark-Simulacrum 
Ignore `build` dir formatting

I've noticed that rustfmt tries to parse and check the formatting of code in `build` if `.git` is missing (which includes test artifacts and generated code). This should fix that.

[docs] remind bug reporters to update nightly

Hi and thanks for rust! Today I reported a bug in nightly that was already fixed, so I thought other potential bug reporters might appreciate a reminder to update before reporting.  I wasn't sure if this would apply for other channels as well.

Rollup merge of #68681 - bobrippling:fix-matched-angle-brackets, r=Centril 
Suggest path separator for single-colon typos

This commit adds guidance for when a user means to type a path, but ends
up typing a single colon, such as `<<Impl as T>:Ty>`.

This change seemed pertinent as the current error message is
particularly misleading, emitting `error: unmatched angle bracket`,
despite the angle bracket being matched later on, leaving the user to
track down the typo'd colon.

Use BufWriter for emitting MIR

I noticed that `--emit=mir` takes long time on a large crate. https://github.com/rust-lang/rust/pull/64344 seem to have fixed `-Zdump-mir`, but not `--emit=mir`.
