Revival of #112105. Add a switch to
FlowGraphDfsTreethat indicates if its traversal used edge likelihoods to determine the order in which successors were visited. This switch can then be used by debug checks that verify the DFS's correctness to check both types of trees. This functionality means we can frequently reuse the DFS tree annotations computed by LSRA throughout block layout.
