Commit ID 8a5a64eac563ff755048d40f6a5046ea4dcf0154

Commit Type Non Functional
Minor cleanup of search.cpp

Four very minor edits. Note that tte->save() uses posKey and
not pos.key() in other places.

Originally I also added a futility_move_counts() function to
make things more consistent with the futility_margin() and
reduction() functions. But then razor_margin[] should probably
also be turned into a function, etc. Maybe a good idea, maybe not.
So I did not include it.

Non functional change.
