Rollup merge of #62680 - ecstatic-morse:fix-dataflow-results-consumer, r=matthewjasper 
Actually call `visit_block_entry` in `DataflowResultsConsumer`

This fixes a trivial bug in `DataflowResultsConsumer`: `visit_block_entry` is never called when visiting dataflow results.

A previous version of #62547 used this API and included this fix, but it has since switched to `DataflowResultsCursor` making this commit irrelevant.

Rollup merge of #62668 - goodmanjonathan:fix-62660, r=estebank 
Fix #62660

If the explicitly given type of a `self` parameter fails to parse correctly, we need to propagate the error rather than dropping it and causing an ICE.

Fixes #62660.

Rollup merge of #62639 - immunant:invariant_valistimpl, r=eddyb 
Make VaListImpl<'f> invariant over the 'f lifetime

After doing some research on variance and going back to look at `VaList` and `VaListImpl`, I realized that `VaList<'a, 'f>` is invariant over the `'f` lifetime (and covariant over `'a`), but `VaListImpl<'f>` isn't invariant but probably should be. This patch makes `VaListImpl<'f>` invariant over `'f`.

Rollup merge of #62634 - llogiq:uninit-array-docs, r=RalfJung 
Less unsafe in the array example of MaybeUninit docs

I believe this is an acceptable way to initialize elements of `[MaybeUninit<T>; _]` arrays. Miri agrees. Conceptually, we are working at the array level, above the `MaybeUninit`, and as we are replacing it wholesale, this should pose no problem to soundness. And the code is easier to read.

pprust: Improve pretty-printing of delimited token groups

The commit "Do not convert attributes into `MetaItem`s for printing" fixes https://github.com/rust-lang/rust/issues/62628.

Other commits fix regressions from abandoning `MetaItem`s, and make formatting for attributes, macro calls, macro definitions and other delimited token groups better and more consistent.
