Annotation Type CXXReference

@Retention(value=RUNTIME)
 @Target(value={TYPE_USE,METHOD,PARAMETER})
public @interface CXXReference

1. If the annotated type is a FFIPointer:
   1. As a parameter: The pointer will be used as a reference (p -> *p) in generated code
   2. As a return value: The reference will be used as a pointer (p -> &p) in generated code
   1. If the annotated type is a FFIMirror:
      1. As a parameter: The mirror value will be used as a reference. The state will be updated accordingly. If no state is needed, use a CXXValue instead.
      2. As a return value: The reference will be used to copy value to a mirror.
   2. Primitives are used the same as the FFIMirror except their values are not updated.
