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