[Dinar Temirbulatov via Phabricator via llvm-commits]

dtemirbulatov added a comment.

Rebased, Removed tree traversal approach and implemented suggestion by Alexey Bataev : "Did you think about recalculating the cost of the reduced tree instead of using a scheme with cost subtraction?", This looks like more efficient than tree traversal.
