Personally I think that check for move out of std::unique_ptr, and check for overall heavy moves could be implemented as an separate one, not related to unique_ptr. Easiest way to detect heavy moves is to check size of object, and above some threshold mark them as heavy. But thats a separate problem. Maybe this PR should be abandoned.
