IMPALA-4269: Codegen merging exchange node

This change enables codegen for the tuple row comparator
used in merging-exchange node.

With this change, merging-exchange operator improves by
40% and 50% respectively for primitive_orderby_bigint and
primitive_orderby_all on TPCH-300, speeding up the query by
6% and 11% respectively.
