Fix race condition btw DelayReferenceRefernent vs Reference.clear().
Rename IsMarkedHeapReference to IsNullOrMarkedHeapReference.
Move the null check from the caller of IsMarkedHeapReference into
IsNullOrMarkedHeapReference.
Make sure that the referent is only loaded once between the null
check and the IsMarked call.
Use a CAS in ConcurrentCopying::IsNullOrMarkedHeapReference when
called from DelayReferenceRefernent.
