Source/WebCore: Ensure timers and other active DOM objects do not fire in suspended documents.
https://bugs.webkit.org/show_bug.cgi?id=53733
ScriptExecutionContext now remembers it has suspended active DOM objects
and suspends all newly installed active DOM objects as well.
All create-calls active DOM objects now calls the post constructor method
suspendIfNeeded that updates the suspend state. It is post constructor
because the suspend/resume functions are virtual and thus can not be called
from constructors.
