        * c-common.c (resolve_overloaded_builtin): Forward to target
        hook for BUILT_IN_MD built-ins.
        * c-typeck.c (finish_call_expr): Call resolve_overloaded_builtin
        for all types of built-in.
        * target-def.h (TARGET_RESOLVE_OVERLOADED_BUILTIN): New.  Use it
        in the definition of the target hooks struct.
        * target.h (struct gcc_target): Add resolve_overloaded_builtin.
        * config/rs6000/altivec.h: Rewritten.
        * config/rs6000/rs6000-c.c (struct altivec_builtin_types,
        altivec_resolve_overloaded_builtin, altivec_build_resolved_builtin,
        rs6000_builtin_type, rs6000_builtin_type_compatible,
        altivec_overloaded_builtins, rs6000_builtin_type,
        rs6000_builtin_type_compatible): New.
        * config/rs6000/rs6000.c (rs6000_builtin_types, rs6000_builtin_decls):
        New.
        (def_builtin): Turn into a function.  Check for duplicates and store
        the builtin into rs6000_builtin_decls.
        (bdesc_3arg, bdesc_dst, bdesc_altivec_preds, bdesc_2arg,
        bdesc_1arg): Add overloaded builtins.
        (altivec_expand_builtin): Check for unresolved overloaded builtins,
        do not support ALTIVEC_COMPILETIME_ERROR.
        (rs6000_init_builtins): Add opaque 128-bit vector, and internal
        nodes to represent front-end types.
        (altivec_init_builtins, rs6000_common_init_builtins): Create builtins
        with opaque arguments and/or return values.
        * config/rs6000/rs6000.h (enum rs6000_builtins): Remove
        ALTIVEC_COMPILETIME_ERROR and add Altivec overloaded builtins.
        (rs6000_builtin_type_index): New.
        (is_ev64_opaque_type): Rename to...
        (rs6000_is_opaque_type): ... this.
        (rs6000_cpu_cpp_builtins): Install the resolve_overloaded_builtin
        target hook.
