2006-10-28split critical edges more carefully and intelligently. In particular, criticalChris Lattner
edges whose destinations are not phi nodes don't bother us. Also, share split edges, since the split edge can't have a phi. This significantly reduces the complexity of generated code in some cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31274 91177308-0d34-0410-b5e6-96231b3b80d8
