I don't like very much the idea of adding `struct kortest_result`. It should
better go in `builtin_test_helpers.h` instead of in a cpp file.
Another option would be to return `std::pair<unsigned char, unsigned char>`,
but we would have to compare then against `__cplusplus >= 201402L` because
`std::pair(U1 &&x, U2 &&x)` is `constexpr` since C++14.
