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
