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.

Revert stabilization of never type

Fixes rust-lang#66757

I decided to keep the separate `never-type-fallback` feature gate, but tried to otherwise revert rust-lang#65355. Seemed pretty clean.

( cc @Centril, author of rust-lang#65355, you may want to check this over briefly )

LinkedList: drop remaining items when drop panics

rust-lang#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.

Remove i686-unknown-dragonfly target

DragonFly BSD removed support for i386 a while ago. It only supports x86_64 right now.
