    [heap] Clean up TypedSlotSet. · 841c40b7
    Ulan Degenbaev authored
    This extracts the parts of the TypedSlotSet that are used only
    sequentially into a separate class called TypedSlots.
    
    The new class will be used in the concurrent marker to keep track of
    typed slots locally and then to merge them to the main remembered set
    during finalization of marking.
    
    The patch also cleans up atomics in the Iterate and ClearInvalidSlots
    methods that can run concurrently to each other.
