JDK-8236696 :  
Lookup::hasPrivateAccess intends to return true for "full-power lookup", i.e. a Lookup produced by the MethodHandles::lookup factory method where the caller class is the lookup class. 

With  JDK-8173978, MODULE bit indicates if this lookup object is created by a member in the same module as the lookup class.   MethodHandles::privateLookupIn can produce a Lookup with MODULE bit dropped if teleporting from another module.

Lookup::hasPrivateAccess should be updated to return true if this lookup has both PRIVATE and MODULE access.
