[PATCH] D57779: [SLP] Add support for throttling.

[Dinar Temirbulatov via Phabricator via llvm-commits]

dtemirbulatov added a comment.

Rebased, removed limiter to minimal subtree hight of 3 elements after correcting getInsertCost() now those examples look good on benchmarking, added cost base estimations when to avoid throttling: "Tree cost" + "All reducible cost" >  -SLPCostThreshold, corrected the error in findSubTree() to sort all positive elements from a tree instead of first n-elements.
