        ("altivec_mfvscr"): Read from VSCR.

        Add vscr sets for the following insns: altivec_vctuxs,
        altivec_vaddubs, altivec_vaddsbs, altivec_vadduhs,
        altivec_vaddshs, altivec_vadduws, altivec_vaddsws, altivec_vctsxs,

        altivec_vmsumshs, altivec_vpkuhss, altivec_vpkshss,
        altivec_vpkuwss, altivec_vpkswss, altivec_vpkuhus,
        altivec_vpkshus, altivec_vpkuwus, altivec_vpkswus,
        altivec_vsububs, altivec_vsubsbs, altivec_vsubuhs,
        altivec_vsubshs, altivec_vsubuws, altivec_vsubsws,
        altivec_vsum4ubs, altivec_vsum4sbs, altivec_vsum4shs,
        altivec_vsum2sws, altivec_vsumsws.

        * config/rs6000/rs6000.h: Add VSCR fixed register.
        (CALL_REALLY_USED_REGISTERS): Add vscr.
        (CALL_USED_REGISTERS): Same.
        (FIXED_REGISTERS): Same.
        (REG_ALLOC_ORDER): Same.
