dup_table_list Tables to be used in ON DUPLICATE KEY
It's either all global tables or only the table we
insert into, depending on if we are using GROUP BY
in the SELECT clause).

be taken from table_list->table)

TODO (in far future)
In cases of:
INSERT INTO t1 SELECT a, sum(a) as sum1 from t2 GROUP BY a
ON DUPLICATE KEY ...
we should be able to refer to sum1 in the ON DUPLICATE KEY part

You MUST set table->insert_values to 0 after calling this function
