        determine_block_size: Set len_rtx to min size if min size == max size

    added

    +    gcc_assert (min_size != max_size
    +           || rtx_equal_p (ops[2].value, ops[6].value));

    But the number of operands isn't fixed and may be less than 7.  Replace
    the min size rtx with GEN_INT (min_size) to support different numbers of
    operands.
