Compare a move_iterator and a move_sentinel.

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::move_iterator<Iter> is an associated class of the arguments.

Parameters

i	-	std::move_iterator<Iter>
s	-	std::move_sentinel<S>, where S models std::sentinel_for<Iter>

Return value

1-2) i.base() == s.base()

3-4) !(i == s)
