You keep saying this, but I doubt it.

For example, branches are typically 25% of code, and those aren't 64-bit.

Nor are loop counters, if you have any loops. Or counters, period. Example: if
you count how many pawns are on white squares. That's not 64-bit.

Or, speaking of your eval function, your score isn't 64-bit. And presumably
you're updating the score frequently. Your piece square tables aren't 64-bit.

I'd like to see actual data instead of handwaving.
