Fix bogus SLP nvector compute in check_load_store_for_partial_vectors
We have a new overload for vect_get_num_copies that handles both
SLP and non-SLP. Use it and avoid the division by group_size
for SLP when not using load-store lanes.
* tree-vect-stmts.cc (check_load_store_for_partial_vectors):
Use the new vect_get_num_copies overload. Only divide by
group_size for SLP for load-store lanes.
