[PATCH] rs6000: Make density_test only for vector version

Hi, When I was investigating density_test heuristics, I noticed that the current rs6000_density_test could be used for single scalar iteration cost calculation, through the call trace: vect_compute_single_scalar_iteration_cost -> rs6000_finish_cost -> rs6000_density_test It looks
