    rs6000: Remove typedef for struct rs6000_cost_data
    
    As Segher pointed out, to typedef struct _rs6000_cost_data as
    rs6000_cost_data is useless, so rewrite it without typedef.
    
    gcc/ChangeLog:
    
            * config/rs6000/rs6000.c (struct rs6000_cost_data): Remove typedef.
            (rs6000_init_cost): Adjust.
