Fix a series of undefined behaviours 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. No functional change.
