   Rationalization: it turns out that HashAggregationQueryWithFallbackSuite is 
more than 11x slower compared to HashAggregationQuerySuite. If the test ran 
fast enough then the elapsed time of HashAggregationQueryWithFallbackSuite is 
acceptable, but sometimes the test ran slow, and 
HashAggregationQueryWithFallbackSuite took more than 11x even for the case (I 
saw 10mins ~ 1hr+ for the suite).
   
   Setting UnsafeAlignedOffset size affects globally, hence it's excluded from 
the matrix.
