Bah, so this boils down to PUSH_ARGS_REVERSED and its affect on gimplification
and thus initial GIMPLE. In this case PUSH_ARGS_REVERSED == 1 "wins".
(for the operator- calls code for b * c and c * d is emitted first)
So we could add an effective target push_args_reversed ... iff that's easy
enough to fill-in. Or explicitely add target matches. Or spend more
time on trying to analyze why order matters for SCCVN here (it's all about
->count CSE).
