type as the vector element type: allow them to be of a wider integer type than the element type all the way through the system, and not just as far as LegalizeDAG. This should be safe because it used to be this way (the old type legalizer would produce such nodes), so backends should be able to handle it. In fact only targets which have legal vector types with an illegal promoted element type will ever see this (eg: <4 x i16> on ppc). This fixes a regression with the new type legalizer (vec_splat.ll). Also, treat SCALAR_TO_VECTOR the same as BUILD_VECTOR. After all, it is just a special case of BUILD_VECTOR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69467 91177308-0d34-0410-b5e6-96231b3b80d8
