The new identity, value, and primitive modifiers are included in java.lang.reflect.Modifier to 
provide straightforward mapping from the VM definitions of the modifier bits to those provided in the API.
Added clarifications to modifier methods to indicate that the source of the modifier bits is significant,
the `isXXX` methods of Modifier only give valid results when the modifier bits come from the respective class, method or field.
