> Given this code doesn't check the optimization level anymore, do you still need separate check prefixes for `O2` and `O0`. Or if that doesn't work for everything, maybe you could share a check prefix for some of the tests? (Maybe it would make sense to check IR generated using `-disable-llvm-passes`.)
The bug only triggered at `O0`, so I still want to test it without optimizations. Note that we do check optimization levels during code generation to determine if we should generate an `is.constant` intrinsic.
