	(compute_antic): ... local here.  Move and fix worklist
	handling here.  Do not clear EDGE_DFS_BACK.
	(compute_antic_aux): Add dumping for MAX assumed succs.  Remove
	worklist handling, dump when ANTIC_IN changed.
	(compute_partial_antic_aux): Remove worklist handling.
	(init_pre): Do not compute post dominators.  Add a comment about
	the CFG order chosen.
