llvm/test/CodeGen/X86/vec_shuffle-18.ll
Chris Lattner 82dd3d38d9 Fix the xfail I added a couple of patches back. The issue
was that we weren't properly handling the case when interior
nodes of a matched pattern become dead after updating chain
and flag uses.  Now we handle this explicitly in 
UpdateChainsAndFlags.
