    libstdc++: Remove workaround for PR c++/78173
    
    Now that the G++ bug is fixed we no longer need to protect this partial
    specialization from complaining about subtracting void pointers.
    
    libstdc++-v3/ChangeLog:
    
            * include/bits/iterator_concepts.h (incrementable_traits<Tp>):
            Remove workaround for PR c++/78173.
