8001028: Improve GC option handling

Browse source 
If there are not enough native resources to create the ReferenceHandler or Finalizer Java threads, the VM will attempt to throw an OOME before the java.lang.Class class has been initialized. This can result in assertion failures and other crashes. Move the initialization of the java.lang.Class class to just before the initialization of the java.lang.ref.Finalizer class.
