* doc/invoke.texi (Option Summary): Add -mvrsave=.
        (RS/6000 and PowerPC Options): Document -mvrsave=.

        * config/rs6000/rs6000.c (rs6000_altivec_vrsave): New global.
        (rs6000_altivec_vrsave_string): Same.
        (rs6000_override_options): Call rs6000_parse_vrsave_option.
        (rs6000_parse_vrsave_option): New.
        (rs6000_stack_info): Only generate vrsave instructions when
        TARGET_ALTIVEC_VRSAVE.

        * config/rs6000/rs6000.h (TARGET_OPTIONS): Add -mvrsave= option.
        (rs6000_altivec_vrsave_string): Define extern.
        (rs6000_altivec_vrsave): Same.
        (TARGET_ALTIVEC_VRSAVE): New.
