I tested and almost all tests passed if I use "avx2" instead of my original "sse2".

Few tests requires "avx512dq":

ArrayTypeConvertTest.convertDoubleToLong()
ArrayTypeConvertTest.convertFloatToLong()
ArrayTypeConvertTest.convertLongToDouble()
ArrayTypeConvertTest.convertLongToFloat()

BasicLongOpTest.vectorAbs() needs "avx512vl"
