This is a follow-on patch to: http://reviews.llvm.org/D7093 That patch canonicalized constant splats as build_vectors, and this patch removes the constant check so we can canonicalize all splats as build_vectors. This fixes the 2nd test case in PR22283: http://llvm.org/bugs/show_bug.cgi?id=22283 The unfortunate code duplication between SelectionDAG and DAGCombiner is discussed in the earlier patch review. At least this patch is just removing code... This improves an existing x86 AVX test and changes codegen in an ARM test.
