[Bug libstdc++/45488] lower_bound iterator must be default constructible

[paolo dot carlini at oracle dot com]

Granted, __middle is not used after the loop, thus moving the declaration
inside the loop seems a tad cleaner. But then we should do the change
consistently for both lower_bound overloads and for upper_bound. Please test
that, simply use _ForwardIterator __middle = __first; and send to the mailing
list a real patch, if you want your name in the ChangeLog. Thanks.
