Jacob Pratt 7913288d66 Rollup merge of #154891 - WaffleLapkin:deregress-manually-drop-matching, r=JohnTitor ...

implement `StructuralPartialEq` for `MaybeDangling`

This fixes -- a stable-to-stable regression where constants of type `ManuallyDrop<T>` would not be allowed to be used as a pattern due to `MaybeDangling<T>` in `ManuallyDrop<T>` not implementing `StructuralPartialEq`.

Fixes https://github.com/rust-lang/rust/issues/154890
