Rollup merge of #76199 - Mark-Simulacrum:void-zero, r=nikomatsakis

Permit uninhabited enums to cast into ints

This essentially reverts part of #6204; it is unclear why that [commit](https://github.com/rust-lang/rust/pull/6204/commits/c0f587de34f30b060df8a88c4068740e587b9340) was introduced, and I suspect no one remembers.

The changed code was only called from casting checks and appears to not affect any callers of that code (other than permitting this one case).

Fixes #75647.
