Owen Anderson a0b59f6bd2 Add a prototype of a new peephole optimizing pass that uses LazyValue info to simplify PHIs and select's. ... This pass addresses the missed optimizations from PR2581 and PR4420. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112325 91177308-0d34-0410-b5e6-96231b3b80d8		2010-08-27 23:31:36 +00:00
