There may be a better way to fix this. The way I've fixed similar problems in this pass is to insert `ub.poison` values. See `createPoisonedValues` and where it's called in this file. The `ub.poison` approach may introduce unnecessary ops (that will be removed again), but it makes the implementation easier to understand and debug. Can you give that a try?
