Avoid SLP_REPRESENTATIVE access for VEC_PERM in SLP scheduling
SLP permute nodes can end up without a SLP_REPRESENTATIVE now,
the following avoids touching it in this case in vect_schedule_slp_node.
* tree-vect-slp.cc (vect_schedule_slp_node): Avoid looking
at SLP_REPRESENTATIVE for VEC_PERM nodes.
