[PATCH] rs6000: Support [u]mul3_highpart for vector

Hi, This patch is to make Power10 newly introduced vector multiply high (part) instructions exploited in vectorized loops, it renames existing define_insns as standard pattern names. It depends on that patch which enables vectorizer to recog mul_highpart. Tested on powerpc64le-linux-gnu P9 with
