This fixes a bug where shuffles were being fused such that the resulting input types were not legal on the target. This would occur only when both inputs and dependencies were also foldable operations (such as other shuffles) and there were other connected pairs in the same block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167731 91177308-0d34-0410-b5e6-96231b3b80d8
