Bug description:Use of SPLObjectStorage Defeats gc_collect_cycles

Description:
------------
Using SPLObjectStorage objects in a cycle will defeat gc_collect_cycles
ability to detect that cycle.

So, if I have an object ParentObject which has an SPLObjectStorage which
attaches a ChildObject that has a reference back to ParentObject, the
garbage collector will never actually collect ParentObject.



Expected result:
----------------
After calling gc_collect_cycles() old objects that no longer have
references should be collected

Actual result:
--------------
Cycles that have SPLObjectStorage in them are not collected
