Detect uninhabited types early in const eval r? `@RalfJung` implements https://github.com/rust-lang/rust/pull/108442#discussion_r1143003840 this is a breaking change, as some UB during const eval is now detected instead of silently being ignored. Users can see this and other UB that may cause future breakage with `-Zextra-const-ub-checks` or just by running miri on their code, which sets that flag by default.
