The introduction of the ProjectSet node has caused the regressionin
the executor visibly. A bisect run is showing me this commit as the
culprit

Move targetlist SRF handling from expression evaluation to new executor node.
I was expecting a leak of some kind first, but valgrind does not
complain when executing the query eating all the memory. Before this
commit the memory usage remains low and stable, less than 1% in my
environments.
