    [PATCH,RS6000 1/5] Clean-up MASK_<xxxx> and RS6000_BTM_<xxxx> definitions.
    
    This patch removes the defines that are no longer used, and
    updates the comment for the set of MASK_<xxxx> defines.
    
    This patch removes the defines for
    MASK_REGNAMES, MASK_PROTOTYPE, RS6000_BTM_ALWAYS, RS6000_BTM_COMMON.
    
    gcc/
            * config/rs6000/rs6000.h (RS6000_BTM_COMMON, RS6000_BTM_ALWAYS,
            MASK_REGNAMES, OPTION_MASK_REGNAMES, MASK_PROTOTYPE,
            OPTION_MASK_PROTOTYPE, MASK_UPDATE, OPTION_MASK_UPDATE): Remove.
