Jingyue Wu 41c8aefa76 SelectionDAG: Prefer to combine multiplication with less uses for fma ... Summary: For example: s6 = s0*s5; s2 = s6*s6 + s6; ... s4 = s6*s3; We notice that it is possible for s2 is folded to fma (s0, s5, fmul (s6 s6)). This only happens when Aggressive is true, otherwise hasOneUse() check already prevents from folding the multiplication with more uses.
