LegalizeDAG: Implement promote for scalar_to_vector This allows avoiding the default Expand behavior which introduces stack usage. Bitcast the scalar and replace the missing elements with undef. This is covered by existing tests and used by a future commit which makes 64-bit vectors legal types on AMDGPU. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@252632 91177308-0d34-0410-b5e6-96231b3b80d8
