S/390: Define vectorization_cost hook
Define the vectorization_cost hook. The only change right now
compared to the default implementation is the reduced costs for
unaligned loads/stores. This is supposed to prevent unnecessary loop
peeling performed to reach better alignments.
Further tuning of this hook is required.
