Thanks for the feedback @bjope, @kparzysz.   I think @bjope has a good point regarding the MI Operands.  
I think we can solve the same issue I'm trying to solve here, by just adding a isDebug check to the operands in addUses.  
I'd also add the same check to removeDefs.  That would make this patch here moot.  If you think that is the more correct
thing to do, and it sounds like it might be, then I'd rather do that.
