I'd personally love to have this pass for the purpose of being able to have an `O0` pipeline that still satisfies the preconditions of dialect conversion, which requires no blocks with no predecessors to be in the IR. Alternatively one could reconsider lifting this precondition, but I'd consider simple DCE like this to a good fit for an O0 pipeline either way.
