Owen Anderson 9200e81a18 SDISel's constant branch folding can fold away self-loops, which doesn't result in any dead blocks, but ... rather an incorrect phi input. Add code to UnreachableMachineBlockElim to get rid of these entries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54432 91177308-0d34-0410-b5e6-96231b3b80d8		2008-08-06 23:16:52 +00:00
