Simplified code in generate_derived_keys() and when using pos_in_tables
Added comments that not used keys of derivied tables will be deleted. Added some comments about checking if pos_in_table_list is 0. Other things: - Added a marker (DBTYPE_IN_PREDICATE) in TABLE_LIST->derived_type to indicate that the table was generated from IN (list). This is useful for debugging and can later be used by explain if needed. - Removed a not needed test of table->pos_in_table_list as it should always be valid at this point in time.
