Use stable sort to make sure bench with TB yields same results everywhere. std::sort() is not stable so different implementations can produce different results: use the stable version instead. Observed for '8/6k1/5r2/8/8/8/1K6/Q7 w - - 0 1' yielding different bench results for gcc and MSVC and 3-4-5 syzygy TB prior to this patch. closes https://github.com/official-stockfish/Stockfish/pull/3083 No functional change.
