Rollup merge of rust-lang#123578 - lqd:regression-123275, r=compiler-errors Restore `pred_known_to_hold_modulo_regions` As requested by `@lcnr` in rust-lang#123275 (comment) this PR restores `pred_known_to_hold_modulo_regions` to fix that "unexpected unsized tail" beta regression. This also adds the reduced repro from rust-lang#123275 (comment) as a sub-optimal test is better than no test at all, and it'll also cover rust-lang#108721. It still ICEs on master, even though https://github.com/phlip9/rustc-warp-ice doesn't on nightly anymore, since rust-lang#122493. Fixes rust-lang#123275. r? `@compiler-errors` but feel free to close if you'd rather have a better test instead cc `@wesleywiser` who had signed up to do the revert Will need a backport if we go with this PR: `@rustbot` label +beta-nominated
