PR tree-optimization/81303
* tree-vect-data-refs.c (vect_get_peeling_costs_all_drs): Pass
in datarefs vector.  Allow NULL dr0 for no peeling cost estimate.
(vect_peeling_hash_get_lowest_cost): Adjust.
(vect_enhance_data_refs_alignment): Likewise.  Use
vect_get_peeling_costs_all_drs to compute the penalty for no
peeling to match up costs.
