In cases like: var foo []io.Writer var buf *bytes.Buffer foo = append(foo, <>) we weren't giving "buf" a good score. When comparing the candidate type *bytes.Buffer to the (variadic) expected type []io.Writer we were turning the candidate type into []*bytes.Buffer. However, of course, []*bytes.Buffer is not assignable to []io.Writer, so the types didn't match. Now we instead turn the expected type []io.Writer into io.Writer and compare to *bytes.Buffer. I fixed the @rank test note to check that the candidates' scores are strictly decreasing. Previously it would allow candidates with the same score if they happened to be in the right order. This made it easier to right a test for this issue, but also uncovered an issue with untyped completion logic. I fixed it to do the untyped constant check if _either_ the expected or candidate type is untyped (previously it required the candidate type to be untyped). Fixes golang/go#35625.
