I agree that `; CHECK-NEXT-NOT: {{.*}}:` is uncommon and doesn't seem particularly useful in this case.
Actually, I think the test has a fair chance that it may bit rot and for maintainability we probably should a comment about the C++ source and some comments about what the test file test.

CC @dblaikie for the `coro-debug.l`l debate. The test was added from D33614 <https://reviews.llvm.org/D33614>.
