Avoid shifting negative signed integers and use typed 
enum to avoids decrementing a variable beyond its defined 
range, like: 
for (Rank r = RANK_8; r >= RANK_1; --r) 

Changes were tested individually and passed SPRT[-3, 1]. 

With this patch gcc --sanitize builds cleanly.

Isa 1.9.8 - winboard chess engine

Isa - winboard chess engine

About engine: Isa is a chess engine I developp during my free time. Chess programming is my hobby since the 80's years. I started developing with QuickBasic 4.5 (I wrote a weak engine named Bishop) .
Then I learned the C langage and studed the TSCP source code (like everyone I think) .
« Titan » and « DCP » (DCP = Titan + winboard protocol) was born . Strengh was always so weak , around 1400 elo .
After that I rewrote again my engine and Jars came out (I released Jars) and then Yoda (both played around 1800-1900 elo.
After finding dificult to improve , I stopped working on both engines and started to work on Isa , a diferent way.
I started Isa from Firstchess.c source.

Output PV if last iteration does not complete 

Instead of outputting "info nodes ... time ..." when the last 
iteration is interrupted, simply call UCI::pv() to output the PV. 

I thought about calling UCI:pv() with bounds -VALUE_INFINITE, VALUE_INFINITE to avoid "lowerbound" or "upperbound" appearing in it, but I'm not sure that would be any better. 

This patch fixes rare inconsistencies between the first move of 
the last PV output and the bestmove played. It also makes sure 
that all the latest statistics are sent to the GUI (not only nodes 
and time but also nps, tbhits, hashfull). 

No functional change.
