Construct object which is initially not reference counted.
The reference counting starts if release() is called.

Start reference counting.
The object is constructed with _refs set to 0, meaning it isn't being reference counted.
Calling release() sets _refs to 1 if it is 0, and from then opt_intrusive_ptr will increment and decrement _refs. If it is decremented to 1, the object is deleted.

Reference count.
This needs to be mutable so we can add/remove references through const pointers.
