Optimize away a branch on the free fastpath. On the rtree metadata lookup fast path, there will never be a NULL returned when the cache key matches (which is unknown to the compiler). The previous logic was checking for NULL return value, resulting in the extra branch (in addition to the cache key match checking). Make the lookup_fast return a bool to indicate cache miss / match, so that the extra branch is avoided.
