Handle SLP_TREE_LANE_PERMUTATION in scalar costing

This properly handles a lane permutation in scalar costing.
For the current only use this doesn't matter much but with
permutes that change the number of lanes it will eventually
ICE.

* tree-vect-slp.c (vect_bb_slp_scalar_cost): Adjust
for lane permutations.
