    layout: Remove freezeUpdateRegions/thawUpdateRegions
    
    Due to a bad rebase causing freezeUpdateCount to never get initialized,
    these functions effectively did nothing. Since we're going to go to a
    different mechanism for freezing region updates, let's just tear these
    out now instead of fixing them before tearing them out.
