 * @assertion Let sb be a break statement. If sb is of the form break L;, then
 * let sE be the the innermost labeled statement with label L enclosing sb. If
 * sb is of the form break;, then let sE be the innermost do, for, switch or
 * while statement enclosing sb. It is a compile-time error if no such statement

 * @description Checks that it is a compile-time error when a break statement of
 * the form "break L;" references a labeled case clause (adjacent or enclosing)
