        PR libstdc++/21172
        * include/bits/stl_heap.h (__adjust_heap(_RandomAccessIterator,
        _Distance, _Distance, _Tp), __adjust_heap(_RandomAccessIterator,
        _Distance, _Distance, _Tp, _Compare)): Avoid potential integer
        overflow.

        * include/bits/stl_heap.h (__is_heap(_RandomAccessIterator,
        _RandomAccessIterator), __is_heap(_RandomAccessIterator,
        _RandomAccessIterator, _StrictWeakOrdering): Mark inline.
        (make_heap(_RandomAccessIterator, _RandomAccessIterator,
        _Compare)): Do not mark inline.

        * include/bits/stl_heap.h (push_heap(_RandomAccessIterator,
        _RandomAccessIterator), sort_heap(_RandomAccessIterator,
        _RandomAccessIterator)): Uncomment __glibcxx_requires_heap.
