oystein.grovlen@sun.com 5af5bb2da6 Bug#51980 mysqld service crashes with a simple COUNT(DISTINCT) query over a view ...

Problem: Segmentation fault in add_group_and_distinct_keys() when accessing
field of what is assumed to be an Item_field object.

Cause: In case of views, the item added to list by is_indexed_agg_distinct() 
was not of type Item_field, but Item_ref.

Resolution:  Add the real Item_field object, the one referred to by 
Item_ref object, to the list, instead.
