For queries with GROUP BY and without hidden GROUP BY fields DISTINCT is
optimized away becuase such queries produce result set without duplicates.
But ROLLUP can add rows which may be same to some rows and this fact was
ignored.

Added check so if ROLLUP is present DISTINCT can't be optimized away.

Solution for 4.0 and 4.1.
If the caller cannot re-open table(s), it gives a NULL
'refresh' argument to open_table(). We used to ignore
flushes then. Now we ignore drops too.
