Why do we need this? Upon returning from move_exprs_to_boundary (in
schedule_expr_on_boundary), we immediately call clear_expr on c_expr which
in turn calls free_history_vect. So the history vector would be cleared
anyways, no? In this case we don't have to export free_history_vect, too.
Otherwise OK.
Thanks,
