        * config/rs6000/altivec.h (vec_dst, vec_dstst, vec_dststt,
        vec_dstt, vec_sld, vec_splat): Add prototypes, marked with
        always_inline attribute.
        * config/rs6000/rs6000.c (altivec_expand_dst_builtin):
        Treat expansion as completed even if literal argument is
        invalid (so that other expansions are not tried in vain).
