> There are known bugs recently found and reported that occur when vectorization is turn
on in Q files.  Until those bugs are fixed, add SET statements to the top of the Q files
that suppress vectorization.
> Change a few EXPLAIN VECTORIZATION to EXPLAIN where it isn't needed and creates an
unnecessary Q file difference during enable by default experiments.
