Subject: [PATCH] For PR1297: Implement "actual" argument types for the
 Intrinsic member functions. This involves changing the getName, getType, and
 getDeclaration methods to have optional parameters for the actual types.
 These are necessary in order for the type/name to be constructed properly for
 overloaded intrinsics. Only the caller knows the actual argument types
 desired.
