rs6000.h (MASK_MFCRF): New. 

* config/rs6000/rs6000.h (MASK_MFCRF): New.
        (TARGET_MFCRF): Test target_flags, not processor type.
        (TARGET_SWITCHES): Add mfcrf and no-mfcrf.
        Change Don't to Do not.
        * config/rs6000/rs6000.c (processors_target_table): Add MASK_MFCRF
        to power4, 970, G5.
