Rollup merge of rust-lang#122318 - compiler-errors:next-solver-tests, r=lcnr
Revision-related tweaks for next-solver tests 1. Add `ignore-compare-mode-next-solver` to any test that already has explicit `current next` revisions, since the test failures when testing with `--compare-mode=next-solver` will be false positives. 2. Explicitly add revisions to a handful of tests where we expect behavior to diverge. r? lcnr
