R600: Add dag combine for copy of an illegal type. This helps avoid redundant instructions to unpack, and repack the vectors. Ideally we could recognize that pattern and eliminate it. Currently v4i8 and other small element type vectors are scalarized, so this has the added bonus of avoiding that. llvm-svn: 213031
