 update_meta_cache() already does a wp_cache_get() on each object_id and
 excludes those that are already in the cache from further processing.
 Later on it does a wp_cache_set().  This can be a wp_cache_add() instead.
 Using adds is preferred policy when priming the cache (as opposed to
 updating the cache when something is changed, which should use set) and
 can improve cache performance in certain scenarios since an add does not
 force invalidation.
