Don't generate tuple deforming functions for virtual slots.
Virtual tuple table slots never need tuple deforming. Therefore, if weknow at expression compilation time, that a certain slot will alwaysbe virtual, there's no need to create a tuple deforming routine forit.Author: Andres FreundDiscussion:https://postgr.es/m/20181105210039.hh4vvi4vwoq5ba2q@alap3.anarazel.de
