bdc6dbbc64 go/types: improve recursive type error message
This change improves error message for recursive types.
Currently, compilation of the [following program](https://go.dev/play/p/3ef84ObpzfG):

package main

type T1[T T2] struct{}
type T2[T T1] struct{}

returns an error:

./prog.go:3:6: invalid recursive type T1
	./prog.go:3:6: T1 refers to
	./prog.go:4:6: T2 refers to
	./prog.go:3:6: T1

With the patch applied the error message looks like:

./prog.go:3:6: invalid recursive type T1
	./prog.go:3:6: T1 refers to T2
	./prog.go:4:6: T2 refers to T1

703bd83623 cmd/compile: use []*Node instead of NodeList in sinit
This is a first of a set of changes to make the transition away from NodeList
easier by removing cases in which NodeList doesn't act semi-trivially like a
[]*Node.

This CL was originally prepared by Josh Bleecher Snyder <josharian@gmail.com>.

This change passes go build -toolexec 'toolstash -cmp' -a std.
