eval.c: copy special exceptions before raise

* eval.c (setup_exception): consider if the exception is frozen,
  but not one of special exception objects.

* gc.c (rb_memerror): copy minimum objects.

* thread.c (rb_threadptr_execute_interrupts): prepare special
  exception queued by another thread to be raised.
