…l_tests_1, r=nnethercote Add reproducibly failing tests for parallel frontend Some tests keep fail with `--parallel-frontend-threads=n`. This PR marks them for tracking and to filter those out for regular tests of the parallel frontend. There are two new similar categories for test failures: `unstable liveness diagnostics` and `pattern matching error message mismatch`. Both of them appear to be just printed diagnostic inconsistencies.
