[PATCH] D61726: [Pass Pipeline] Run another round of reassociation after loop pipeline

-O3 makes sense, probably. I mean, reassociate is unlikely to hurt performance, but a second reassociate pass is unlikely to help much unless some pass like unrolling generates new code after the first reassociate.
