ci: Remove Travis/AppVeyor configuration
Now that we've fully moved to Azure Pipelines and bors has been updated
to only gate on Azure this commit removes the remaining Travis/AppVeyor
support contained in this repository. Most of the deletions here are
related to producing better output on Travis by folding certain
sections. This isn't supported by Azure so there's no need to keep it
around, and if Azure ever adds support we can always add it back!
Cancel unemitted diagnostics during error recovery

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.
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.
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`.

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.

Remove never_type feature requirement for exhaustive patterns
I **think** this resolves#51221
At least for me, it doesn't ICE anymore and all tests are still passing, so LGTM

Update stdsimd to stdarch
The stdsimd repository no longer lives in `rust-lang-nursery/stdsimd` but now lives in `rust-lang/stdarch` instead. This PR updates the stdsimd submodule to the stdarch master branch.
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.

Do not emit type errors after parse error in last statement of block
When recovering from a parse error inside a block, do not emit type
errors generating on that block's recovered return expression.
Fix#57383.
