+// BreakCriticalEdges pass - Break all of the critical edges in the CFG by
+// inserting a dummy basic block.  This pass may be "required" by passes that
+// cannot deal with critical edges.  For this usage, the structure type is
+// forward declared.  This pass obviously invalidates the CFG, but can update
+// dominator trees.
