GEODE-1886: optimize off-heap reference checks

EntryEventImpl now tests the region's off-heap boolean
before it will ask if the new/old value is an instanceof
StoredObject.


> StoredObject instanceof checks in EntryEventImpl slow down heap operations

> The instanceof checks added to EntryEventImpl for offheap have slowed down 
> the performance of heap. This slow down will probably only be noticed when 
> the cache operation is local. When the operations is distributed the network 
> adds enough overhead that the extra time in the instanceof checks is not 
> noticed.
