[PATCH] D17430: [ifcnv] Add comment explaining why it's OK to duplicate convergent MIs in ifcnv.

resistor added a comment.

Ok, I see what you're trying to get at, and I agree with your assessment that a it is removing a control dependence.  Since it's specific to exactly the transform being applied, I think a little deeper explanation in the comment is merited.
