Fix for ​https://bugs.webkit.org/show_bug.cgi?id=39575
Make JS DOMObject inherit from JSObjectWithGlobalObject instead of JSObject

Reviewed by Oliver Hunt.

JavaScriptCore:

Expose the global object stored in JSObjectWithGlobalObject.

  • runtime/JSObjectWithGlobalObject.h:

WebCore:

  • Changes JSDOMWindowShell to inherit from JSObject instead of DOMObject since it doesn't ever go into any DOMObject tables. In a separate change, we may want to make this inherit from JSObjectWithGlobalObject since JSDOMWindowShell does store a global object pointer.
  • Change DOMObject to inherit from JSObjectWithGlobalObject instead of JSObject. In this change I am keeping around DOMObjectWithGlobalPointer, which now just uses the capabilities of JSObjectWithGlobalObject instead of implementing them itself. DOMObjectWithGlobalPointer will go away in a subsequent patch.
