Disable MSVC optimizations for AVX512 GET_CHUNK_MAG #1883

MSVC compiler (VS 17.11.x) incorrectly optimizes the GET_CHUNK_MAG code on
older versions. Appears to be resolved in VS 17.13.2. The compiler would
optimize the code in such a way that it would cause a decompression failure.
It only happens when /Os flag is set.
