Workaround using unaligned loads for gcc < 9 despite usage of alignas, the generated (avx2/avx512) code with older compilers needs to use unaligned loads with older gcc (e.g. confirmed crash with gcc 7.3/mingw on abrok). Better performance thus requires gcc >= 9 on hardware supporting avx2/avx512 closes https://github.com/official-stockfish/Stockfish/pull/2969 No functional change
