Fix the BinaryPredicate form of std::is_permutation to not rely on operator== According to [1], forms 2 and 4 of std::is_permutation should use the passed in binary predicate to compare elements. operator== should only be used for forms 1 and 3 which do not take a binary predicate. This CL fixes forms 2 and 4 which relied on operator== for some comparisons. [1] http://en.cppreference.com/w/cpp/algorithm/is_permutation Patch by Thomas Anderson!
