I didn't do promotions in quiescent search/SEE. I just added it. These
are my test results:

[...]

Warning: node count is different!

Node count is for same depth only.

At best, it's not going to make a lot of difference whether you
do it or not.

This is tricky for me too. If I keep them, I'm going 7% slower
overall. On the other hand, I _know_ I will be seeing some stuff a ply
earlier.

The question is now how often do I think it will happen where it matters.

I have no idea.
