Maybe at some point we enforce GUID presence, but I think we're a ways off from that, so in the mean time we should just ensure we can handle arbitrary legal IR in llvm-reduce.

Do we know why it might not have GUID metadata? Is it a reducer artifact? I.e. should the reducer know not the remove GUID if present?
