df9e491fb2 Rollup merge of #67026 - Nadrieril:improve-usefulness-empty, r=varkor,Centril,estebank 
Improve diagnostics and code for exhaustiveness of empty matches

There was a completely separate check and diagnostics for the case of an empty match. This led to slightly different error messages and duplicated code.
This improves code reuse and generally clarifies what happens for empty matches. This also clarifies the action of the `exhaustive_patterns` feature, and ensures that this feature doesn't change diagnostics in places it doesn't need to.

a2a077460b Look for "unstable feature" error code in test 
Conditionals and loops now have unstable features, and `feature_err` has
its own error code. I think that `feature_err` should take an error code
as a parameter, but don't have the energy to make this change throughout
the codebase. Also, the error code system may be torn out entirely.

ac0bd42a4a Rollup merge of #67250 - nnethercote:rm-DelimSpan-from-NamedMatch-MatchedSeq, r=Centril 
Remove the `DelimSpan` from `NamedMatch::MatchedSeq`.

Because it's unused. This then allows the removal of
`MatcherPos::sp_open`. It's a tiny perf win, reducing instruction counts
by 0.1% - 0.2% on a few benchmarks.

LinkedList: drop remaining items when drop panics

https://github.com/rust-lang/rust/pull/67235, but for `LinkedList`, which has the same issue.

I've also copied over the other drop-related tests from `VecDeque` since AFAICT `LinkedList` didn't have any.

2ca7b7e539 Rollup merge of #66341 - crgl:vec-deque-extend, r=Amanieu 
Match `VecDeque::extend` to `Vec::extend_desugared`

Currently, `VecDeque::extend` [does not reserve at all](https://github.com/rust-lang/rust/pull/65069#discussion_r333166522). This implementation still runs a check every iteration of the loop, but should reallocate at most once for the common cases where the `size_hint` lower bound is exact. Further optimizations in the future could improve this for some common cases, but given the complexity of the `Vec::extend` implementation it's not immediately clear that this would be worthwhile.
