        * config/aarch64/aarch64-cores.def: Rewrite so IMP and PART are
        integer constants.
        * config/aarch64/driver-aarch64.c (struct aarch64_core_data): Change
        implementer_id to unsigned char.
        Change part_no to unsigned int.
        (AARCH64_BIG_LITTLE): New define.
        (INVALID_IMP): New define.
        (INVALID_CORE): New define.
        (cpu_data): Change the last element's implementer_id and part_no to
        integers.
        (valid_bL_string_p): Rewrite to ..
        (valid_bL_core_p): this for integers instead of strings.
        (parse_field): New function.
        (contains_string_p): Rewrite to ...
        (contains_core_p): this for integers and only for the part_no.
        (host_detect_local_cpu): Rewrite handling of implementation and
        par num to be integers; simplifying the code.
