I added pop-state-event-constructor.html in this bug (https://bugs.webkit.org/show_bug.cgi?id=67977), but some tests are crashing or failing. 

- The following test cases are failing, as you can see in the attached file. The IDL type of PopStateEvent.state should be 'any' (http://www.whatwg.org/specs/web-apps/current-work/#popstateevent), and the IDL spec of 'any' (http://www.w3.org/TR/WebIDL/#es-any) says that the following test cases should pass.

    FAIL new PopStateEvent('eventType', { state: '' }).state should be undefined (of type undefined). Was  (of type string).
    FAIL new PopStateEvent('eventType', { state: object1 }).state should be [object Object]. Was [object Object].
    FAIL new PopStateEvent('eventType', { state: {valueOf: function () { return object2; } } }).state should be [object Object]. Was [object Object].
    FAIL new PopStateEvent('eventType', { bubbles: true, cancelable: true, state: object3 }).state should be [object Object]. Was [object Object].

- When we pass a DOM object (i.e. an unserializable object) as follows, then DRT crashes. This crash happens only in DRT.

    shouldBe("new PopStateEvent('eventType', { state: document }).state", "document");

The reason for these failures and crash is that PopStateEvent.state is implemented just as SeriazliedScriptValue, and thus it cannot handle ScriptValue. I am preparing a patch for fixing this.
