 *  Let S be the statement targeted by the continue. If L is not present, this
 *  is the innermost do, for, or while statement. Otherwise it is the do, for,
 *  or while statement with a label matching L, or the switch statement
 *  containing a switch case with a label matching L.

 *  Update continue(S) = join(continue(S), before(N)).
