    Great Sink Refactor
    
    The actions now actively mark wanted nodes so that useless use errrors
    will be suppressed on those nodes.  This marking is recursive on the last
    statement of a statement list.  The optimizer now pays more attention to
    such annotations when traversing children.  Also, we now distinguish
    children that default to void (Stmts, Stmt, Block) from those that default
    to using the child values they calculate (Op, etc.).
