    [PR99663] Don't use unknown constraint for address constraint in
process_address_1.

    s390x has insns using several alternatives with address constraints.  Even
    if we don't know at this stage what alternative will be used, we still can
say
    that is an address constraint.  So don't use unknown constraint in this
    case when there are multiple constraints or/and alternative.
