I ran `-analyze -scalar-evolution` on this test and it indeed works slowly. It doesn't hang, though. It's just extremely slow work due to exponential behavior during range inference. Not obvious that it is somehow caused by trunc inference. Pretty sure it's possible to construct same test without trunc/sexts.
