        PR target/80101
        * config/rs6000/power6.md: Replace store_data_bypass_p calls with
        rs6000_store_data_bypass_p in seven define_bypass directives and
        in several comments.
        * config/rs6000/rs6000-protos.h: Add prototype for
        rs6000_store_data_bypass_p function.
        * config/rs6000/rs6000.c (rs6000_store_data_bypass_p): New
        function implements slightly different (rs6000-specific) semantics
        than store_data_bypass_p, returning false rather than aborting
        with assertion error when arguments do not satisfy the
        requirements of store data bypass.
        (rs6000_adjust_cost): Replace six calls of store_data_bypass_p with
        rs6000_store_data_bypass_p.
