(11) RFR (XS) JDK-8196889: VS2017 Unable to Instantiate OrderAccess::release_store with an Incomplete Class Within an Inlined Method

[Lois Foltan]

Please review this small fix for a VS2017 compilation error.  The 
inaccessibility of the private Atomic::IsPointerConvertible in the 
template arguments for the partial specialization of Atomic::StoreImpl 
causes a (C2027) compilation error indicating a use of an undefined type 
has occurred.  This issue manifests itself only in certain coding 
scenarios, for example, when OrderAccess::release_store() is called from 
within an inlined method of a class where one of the types used to 
instantiate is the currently being defined class.
