History
Gagan Goel f167a6e505 MCOL-4617 Move in-to-exists predicate creation and injection into the engine. 
We earlier leveraged the server functionality provided by

Item_in_subselect::create_in_to_exists_cond and
Item_in_subselect::inject_in_to_exists_cond

to create and inject the in-to-exists predicate into an IN
subquery's JOIN struct. With this patch, we leave the IN subquery's
JOIN unaltered and instead directly perform this predicate creation
and injection into ColumnStore's select execution plan.
