unknown 4144543006 Bug #17212 results not sorted correctly by ORDER BY when using index ...

* don't use join cache when the incoming data set is already ordered
    for ORDER BY
    This choice must be made because join cache will effectively
    reverse the join order and the results will be sorted by the index
    of the table that uses join cache.
