    LoongArch: NFC: Deduplicate crc instruction defines
    
    Introduce an iterator for UNSPEC_CRC and UNSPEC_CRCC to make the next
    change easier.
    
    gcc/ChangeLog:
    
            * config/loongarch/loongarch.md (CRC): New define_int_iterator.
            (crc): New define_int_attr.
            (loongarch_crc_w_<size>_w, loongarch_crcc_w_<size>_w): Unify
            into ...
            (loongarch_<crc>_w_<size>_w): ... here.
