If we have whole program view, use that to upgrade requests for "necessary" types to "constructed" types if we know a constructed was seen during scanning. This avoids RyuJIT seeing a constructed and necessary symbol for the same type. If we don't have whole program view, forgo the optimization and use maximally loadable types instead of necessary types.
