[PowerPC] Check if the pre-increment PHI Node already exists Preparations to use the per-increment are sometimes done in the target independent pass Loop Strength Reduction. We try to detect them in the PowerPC specific pass so that they are not done twice and so that we do not add PHIs that are not required.
