[PATCH] D34889: [ScheduleDAG] Fix bug in check for use of dead defs

I do have a reproducer for this (a .ll test). I've attempted to turn this into a .mir test, but it is too fragile to allow me to change the target specific intrinsics to something generic (required in order to print out the .mir).
Hopefully, the check is an obvious omission and an easy one to approve? 
If not I'll see if I can create a smaller regression for it - but I've already spent quite a lot of time attempting to do this.
