      Bug#13340270: assertion table->sort.record_pointers == __null
      
      bug#12694872 fixed a memory leak in Unique::get(), but did not expect
      Unique::get() to be called twice before the end of the query, where
      buffers are freed.
      
      The solution to this problem is to free the filesort buffers if the
      Unique object is reused.

        Added test case for bug#13340270

      fix for Bug#13335170 - ASSERT IN PLAN_CHANGE_WATCHDOG::~PLAN_CHANGE_WATCHDOG() ON SELECT DISTINCT 
      the "no_changes" parameter of test_if_skip_sort_order() was not honoured.
     @ sql/sql_select.cc
        The bug is in test_if_skip_sort_order(): tab->select->quick
        is not NULL upon entrance, then in this block:
          {
            uint best_key_parts= 0;
            ...
            if (best_key >= 0)
            {
                ...
                select->quick= 0;
                select->test_quick_select(join->thd, ...
        the assignment sets tab->select->quick to NULL. Even if "no_changes" is true.
        Thus, we have a plan change which is not allowed, and Plan_change_watchdog barks...
        The fix is to always restore to "save_quick" is "no_changes" is true.
        
        Misc other changes:
        - return before setting local variables
        - improving one comment
