Bug 1389582. Drop classinfo stuff from Exception, since that's exposed via...

  // for our instance's pointer to our nsIClassInfo will always return null.

  // This is bad because it means that wrapped exceptions will never have a

  // shared prototype. So... We force one to be created via the factory

  // *once* and then go about our business.
