Share empty `Vec`s more within `MatcherPos::matches`.
`create_matches` creates a `Vec<Rc<Vec<NamedMatch>>>`. Even though all the inner `Vec`s are empty, each one is created separately. This commit changes `create_matches` so it instead creates one empty inner `Vec`, and shares it. The commit also changes `MatcherPos::matches` to a boxed slice, because its length doesn't change.
