Auto merge of #42068 - petrochenkov:ustab, r=nikomatsakis
Stabilize unions with `Copy` fields and no destructor What else is needed: - [x] Documentation (https://github.com/rust-lang-nursery/reference/pull/57). - [x] Making assignments to `Copy` union fields safe (https://github.com/rust-lang/rust/pull/42083). - [ ] Backport? (The "stabilization decision" is from [Apr 13](https://github.com/rust-lang/rust/issues/32836#issuecomment-294018091), it's just this PR is late.) cc https://github.com/rust-lang/rust/issues/32836 r? @nikomatsakis
