Auto merge of #45394 - davidtwco:rfc-2008, r=petrochenkov
RFC 2008: Future-proofing enums/structs with #[non_exhaustive] attribute This work-in-progress pull request contains my changes to implement [RFC 2008](https://github.com/rust-lang/rfcs/pull/2008). The related tracking issue is #44109. As of writing, enum-related functionality is not included and there are some issues related to tuple/unit structs. Enum related tests are currently ignored. WIP PR requested by @nikomatsakis [in Gitter](https://gitter.im/rust-impl-period/WG-compiler-middle?at=59e90e6297cedeb0482ade3e).
