BUILD_VECTOR nodes, e.g.: (concat_vectors (BUILD_VECTOR a1, a2, a3, a4), (BUILD_VECTOR b1, b2, b3, b4)) -> (BUILD_VECTOR a1, a2, a3, a4, b1, b2, b3, b4) This fixes an issue with AVX, where a sequence was not recognized as a 256-bit vbroadcast due to the concat_vectors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201158 91177308-0d34-0410-b5e6-96231b3b80d8
