    aarch64: Fix qualifier sequences for cinc/cinv/cneg
    
    The three-operand cinc/cinv/cneg instructions were incorrectly specified
    with the same qualifier sequences as the four-operand variants, which
    resulted in their third operand having an incorrect qualifier specified.
    This works fine while AARCH64_OPND_QLF_NIL is treated as a wildcard, but
    will break when that behaviour is removed.
    
    Fix this by using QL_R2NIL instead.
