    Decouple root visitors from object visitors. · e671ed36
    ulan authored
    This patch adds a new interface called RootVisitor and changes the root
    iteration functions to accept a RootVisitor instead of an ObjectVisitor.
    
    Future CLs will change ObjectVisitor to provide the host object to all
    visiting functions, which will bring it in sync with static visitors.
    
    Having separate visitors for roots and objects removes ambiguity in
    VisitPointers and reduces chances of forgetting to record slots.
    
    This is intended as pure refactoring. All places that require behavior
    change are marked with TODO and will addressed in future CLs.
