Remove two xors by setting the hash keys for unreachable squares to zero performance before: 3.6714 +- 0.20% Gcycles 3.6620 +- 0.12% Gcycles 3.6704 +- 0.26% Gcycles 3.6602 +- 0.27% Gcycles 3.6799 +- 0.37% Gcycles after: 3.6540 +- 0.30% Gcycles 3.6388 +- 0.25% Gcycles 3.6557 +- 0.17% Gcycles 3.6449 +- 0.15% Gcycles 3.6460 +- 0.26% Gcycles (every line is a different `profile-build` and shows the number of cycles needed for `./stockfish bench`, measured with `perf stat -r 10`) closes https://github.com/official-stockfish/Stockfish/pull/5754 No functional change
