    Debug: Refactor handling of unwinding points
    
    We now wrap the set of unwinding points within a block in a newtype to
    mark the fact that they must be sorted by the order that the labels
    occur in the block. Moreover, we fix an oversight in the
    previous design where unwind information would be duplicated while
    propagating unwinding information from predecessor blocks.
