We match the pattern "x >= y ? x-y : 0" into "subus x, y" and two special cases if y is a constant. DAGCombiner canonicalizes those so we first have to undo the canonicalization for those cases. The pattern occurs in gzip when the loop vectorizer is enabled. Part of PR14613. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170273 91177308-0d34-0410-b5e6-96231b3b80d8
