    intel: Migrate handle/name lookups from linear lists to hashtables

    Walking a linear list to find a matching PRIME handle or flinked name
    does not scale and becomes a major burden with just a few objects.
    That said, the fixed size hash is not much better, it just buckets the
    look into a few separate chains rather than one long one.
