   Collect built-in data type handlers for comparison.
   This method is very similar to item_cmp_type() defined in item.cc.
   Now they coexist. Later item_cmp_type() will be removed.
   In addition to item_cmp_type(), this method correctly aggregates
   TIME with DATETIME/TIMESTAMP/DATE, so no additional find_date_time_item()
   is needed after this call.
