Represents a class type in Objective C.

Every Objective C type is a combination of a base type, a set of type arguments (optional, for parameterized classes) and a list of protocols.

Given the following declarations:

'C' is an ObjCInterfaceType C. It is sugar for an ObjCObjectType with base C and no protocols.

'C

' is an unspecialized ObjCObjectType with base C and protocol list [P]. 'C<C*>' is a specialized ObjCObjectType with type arguments 'C*' and no protocol list. 'C<C*>

' is a specialized ObjCObjectType with base C, type arguments 'C*', and protocol list [P].

'id' is a TypedefType which is sugar for an ObjCObjectPointerType whose pointee is an ObjCObjectType with base BuiltinType::ObjCIdType and no protocols.

'id

' is an ObjCObjectPointerType whose pointee is an ObjCObjectType with base BuiltinType::ObjCIdType and protocol list [P]. Eventually this should get its own sugar class to better represent the source.
