[PATCH] critical-anti-dependency breaker: don't use reg def info from kill insts (PR20308)

[Bill Schmidt]

Actually, you do need to add willschm as a reviewer, as he is the person who committed the patch in the previous comment.  I don't immediately see how to add one myself, so will let you handle it...  sorry, Phabricator n00b here.
