Shouldn't the expectations be the same for all optimization levels actually?

If you do need to differentiate some expectations by level, you could do  `--check-prefixes=CHECK,CHECK-O0`, `--check-prefixes=CHECK,CHECK-O1` etc. and then use `CHECK` for the shared expectations, and `CHECK-O<n>` for the level-specific ones. But I'm not sure that's needed here.
