    aarch64: Handle SVE attributes in comp_type_attributes [PR100270]

    Even though "SVE type" and "SVE sizeless type" are marked as
    affecting type identity, the middle end doesn't truly believe
    it unless we also handle them in comp_type_attributes.

            * config/aarch64/aarch64.c (aarch64_comp_type_attributes): Handle
            SVE attributes.
