Previously we were only connecting a closure constraint to type variables from param decls that it referenced. This worked fine up until we started type-checking for-in statements entirely in the constraint system, meaning that closures can now reference type variables from the element pattern. Tweak the collection logic to consider vars too. Resolves rdar://62339835
