[PR93762,PR100651]

            PR fortran/93762
            PR fortran/100651
            * trans-array.cc (gfc_trans_deferred_array): Add presence check
            for optional deferred-length character dummy arguments.
            * trans-expr.cc (gfc_conv_missing_dummy): The character length for
            deferred-length dummy arguments is passed by reference, so that
            its value can be returned.  Adjust handling for optional dummies.
