4bb5d35659 Auto merge of #56392 - petrochenkov:regensym, r=oli-obk 
Delay gensym creation for "underscore items" (`use foo as _`/`const _`) until name resolution

So they cannot be cloned by macros. See https://github.com/rust-lang/rust/pull/56303 for the discussion.

Mostly fix cross-crate use of underscore items by inverting the "gensyms are lost in metadata" bug as described in https://github.com/rust-lang/rust/pull/56303#issuecomment-442464695.
Fix unused import warnings for single-segment imports (first commit) and `use crate_name as _` imports (as specified in https://github.com/rust-lang/rust/pull/56303#issuecomment-442274118).
Prohibit accidentally implemented `static _: TYPE = EXPR;` (cc https://github.com/rust-lang/rust/pull/55983).
Add more tests for `use foo as _` imports.

Stabilise exhaustive integer patterns

This is dependent on the FCP for https://github.com/rust-lang/rfcs/pull/2591 being completed, but that should happen tomorrow, so there's little harm in opening this PR early.

Closes #50907.

b817d0b651 Auto merge of #56110 - varkor:inhabitedness-union-enum, r=cramertj 
Consider references and unions potentially inhabited during privacy-respecting inhabitedness checks

It isn't settled exactly how references to uninhabited types and unions of uninhabited types should act, but we should be more conservative here, as it's likely it will be permitted to soundly have values of such types.

This will also be more important in light of the changes at https://github.com/rust-lang/rust/pull/54125.
