Why size_t? It makes no sense. Maybe you want uintmax_t? Note that you probably
don't want uintptr_t, I believe all of these operations (shifts and casts) are
technically undefined behavior on uintptr_t, and it might be the wrong size
anyway.

     return static_cast<uint16_t>((value >> 8) | (value << 8));
