    [965] Bring back no-backing-store hack for classic-mode performance.
    
    This is not the complete version of the previous hack -- most importantly,
    the NO_FENCE_SUBDATA is missing.  However, the previous implementation of that
    lacked some required synchronization for the state cache.
    
    This improves openarena performance by almost 50%, to about a quarter of what
    it was before bufmgr conversion.
