Benjamin Kramer 8d191a2586 X86: Add a couple of target-specific dag combines that turn VSELECTS into psubus if possible.
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.
