      Fix for BUG#8532. · 03e7620d
      timour@mysql.com authored
      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.
