Write new UT tests that use random data and intentional isRepeating batches to checks for NULL and Wrong Results for vectorized filter and compare.
1) 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 IF vectorized expression classes.
