Cast a shifted_ptr of type ownership to a garbage collected one because the
information on the pointee is not the same.

... When the garbage collector is just in its "collecting" stage.  I do not
wish to start benchmarking every collector, I just wanted to mix reference
counting with garbage collection for a better overall.

Would you like me to rename shifted_ptr to gc_ptr since "shifted" was used
as a warning but not needed anymore since make_gc_ptr is going to be used &
os_collector will be discarded?
