LGTM. Thanks for tidying them up.
Initially, the check prefix `CHECK-UNROLL` was intended to distinguish it from the flatten-based lowering method that would be introduced later, something like `CHECK-FLATTEN`. However, the flatten strategy was later tested in another file and I forgot to clean them up...
