Support Function for Selectivity

Description

Fun quirk of using support functions instead of inlined op+function combination: instead of getting operator selectivity in our join/filters we are now getting the function selectivity. That means they are WRONG, very WRONG. So now we need to bind the support functions into the usual selectivity mechanisms so they can return correct selectivity. Hopefully support functions and selectivity understand join context as well as scan context.
