Tweak API of new function clause_is_computable_at().
Pass it the RestrictInfo under consideration, not just theclause_relids. This should save some trivial amount ofcode at the call sites, and it gives us more flexibilityabout what clause_is_computable_at() does. There's noactual functional change here, though.Discussion:https://postgr.es/m/3564467.1684352557@sss.pgh.pa.us
