Chris Lattner 94f4032448 Make loop-simplify produce better loops by turning PHI nodes like X = phi [X, Y] ... into just Y. This often occurs when it seperates loops that have collapsed loop headers. This implements LoopSimplify/phi-node-simplify.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22746 91177308-0d34-0410-b5e6-96231b3b80d8		2005-08-10 02:07:32 +00:00
