    Description

      Create a template to generate classes to handle comparisons with a scalar on the left and a column on the right.

      This allows queries similar to the following to run vectorized:

      select l_orderkey, l_shipmode
      from lineitem_orc
      where l_orderkey = 1 and 'M' > l_shipmode;
