Simplify stats assignment for Pv nodes This patch is a simplification of my recent elo gainer. Logically the Elo gainer didn't make much sense and this patch simplifies it into smth more logical. Instead of assigning negative bonuses to all non-first moves that enter PV nodes we assign positive bonuses in full depth search after LMR only for moves that will result in a fail high - thus not assigning positive bonuses for moves that will go to pv search - so doing "almost" the same as we do in master now for them. Logic differs for some other moves, though, but this removes some lines of code.
