Muir Manders 6f4f008689 internal/lsp/source: improve completion in switch cases
Now we downrank candidates that have already been used in other switch
cases. For example:

    switch time.Now().Weekday() {
    case time.Monday:
    case time.<> // downrank time.Monday
    }

It wasn't quite as simple as tracking the seen types.Objects.
Consider this example:

    type foo struct {
      i int
    }

    var a, b foo

    switch 123 {
    case a.i:
    case <>
    }

At <> we don't want to downrank "b.i" even though "i" is represented
as the same types.Object for "a.i" and "b.i". To accommodate this, we
track having seen ["a", "i"] together. We will downrank "a.i", but not
"b.i".

I applied only a minor 0.9 downranking when the candidate has already
been used in another case clause. It is hard to know what the user is
planning. For instance, in the preceding example the user could intend
to write "a.i + 1", so we mustn't downrank "a.i" too much.
