Previously, -fshow-overloads=best always showed 4 candidates. The problem is, when this isn't enough, you're kind of up a creek; the only option available is to recompile with different flags. This can be quite expensive! With this change, we try to strike a compromise. The *first* error with more than 4 candidates will show up to 32 candidates. All further errors continue to show only 4 candidates. The hope is that this way, users will have *some chance* of making forward progress, without facing unbounded amounts of error spam.
