> Write new UT tests that use random data and intentional isRepeating batches
> to checks for NULL and Wrong Results for vectorized filter and compare.
> BUGS:
> 1)Â LongColLessLongColumn SIMD optimization do not work for very large
> integers:
> -7272907770454997143 < 8976171455044006767
> outputVector[i] = (vector1[i] - vector2[i]) >>> 63;
> Produces 0 instead of 1...
> Also, add DECIMAL_64 testing. Add missing DECIMAL/DECIMAL_64 Comparison and
