Zia Ansari 02da4e7721 [X86] - Catch extra combine opportunities for redundant imuls. ... When we fold "mul ((add x, c1), c1)" -> "add ((mul x, c2), c1*c2)", we bail if (add x, c1) has multiple users which would result in an extra add instruction. In such cases, this patch adds a check to see if we can eliminate a multiply instruction in exchange for the extra add. I also added the capability of doing the existing optimization with non-splatted vectors (splatted also works).
