rs6000.c (rs6000_stack_info): Always set vrsave_mask for TARGET_ALTIVEC_ABI.

2012-11-19  Mans Rullgard  <mans@mansr.com>

        * config/rs6000/rs6000.c (rs6000_stack_info): Always set vrsave_mask
        for TARGET_ALTIVEC_ABI.  Zero vrsave_save_offset if
        !TARGET_ALTIVEC_VRSAVE.
        (rs6000_emit_prologue): For SAVE_INLINE_VLRs, check vrsave_size
        not vrsave_mask.
