Fix for bug #9798: Rollup crash with InnoDB in setup_sum_funcs().
Disable mix/max group by optimization for queries with rollup for now.
Note: the actual bug was hidden; if this optimization works with rollup
queries we will have to change some code:
the problem is that we call the join->make_sum_func_list() function against
changed thd->mem_root (see SQL_SELECT::test_quick_select()) which creates some
items for rollup, then we free that mem_root, then we try to reuse (free) those
items.

The problem was in that the code that analyses the applicability of the
QUICK_GROUP_MIN_MAX access method for DISTINC queries assumed that there
are no duplicate column references in the DISTINCT clause, and it added
non-exiting key parts for the duplicate column references.
The solution adds a test to check whether the select list already contained
a field with the same name. If such field was already present, then it was
already decided to use its key part for index access. In this such case we
must skip the duplicate field instead of counting it as a new field.
