If a function type has no type parameters, note when it is visited and do not recur. (It must be visited at least once because of closures and their associated types occurring in a generic context). Fixes #51832. Change-Id: Iee20612ffd0a03b838b9e59615f4a0206fc8940b Reviewed-on: https://go-review.googlesource.com/c/go/+/406714 Reviewed-by: Keith Randall <khr@google.com>
