Admit defeat and realize that one simply cannot win against Windows. Use the pattern with both separators in the tests and remove the hack in PathSanitizingFileCheck because it created false positives, some of them could not have been easily fixed. Sadly lit substitutions or other tricks in lit.cfg will not work, because CHECK lines are not processed by lit, but by FileCheck.
