Description

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) 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.
