   It looks like LLVM-15 removed the function. We need to backport this for release branches.
   
   ```
   ../../include/tscore/IntrusivePtr.h:333:29: error: no template named 'binary_function' in namespace 'std'; did you mean '__binary_function'?
     class Order : public std::binary_function<IntrusivePtr<T>, IntrusivePtr<T>, bool>
                          ~~~~~^~~~~~~~~~~~~~~
                               __binary_function
   /usr/local/opt/llvm/include/c++/v1/__functional/binary_function.h:49:1: note: '__binary_function' declared here
   using __binary_function = __binary_function_keep_layout_base<_Arg1, _Arg2, _Result>;
   ^
   ```
   
   BTW, std::binay_function was "deprecated in C++11" and "removed in C++17".
