Hello~ @lucas-rami  Can I change this lit test to only check it compiles successfully? After my commit, `DAG.MinOccupancy` increase from 3 to 4(which I think benefits performance), so the testcase won't pass anymore.  The files used to cause compiler core dump before your commit. As the testcase is sensitive to scheduler results, can I just check it compiles successfully?
