Chris Lattner e4412c1f0b implement an instcombine xform needed by clang's codegen ... on the example in PR4216. This doesn't trigger in the testsuite, so I'd really appreciate someone scrutinizing the logic for correctness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92458 91177308-0d34-0410-b5e6-96231b3b80d8		2010-01-04 06:03:59 +00:00
