r600: add span support for 1D tiles
1D tile span support for depth/stencil/color/textures Z and stencil buffers are always tiled, so this fixes sw access to Z and stencil buffers. color and textures are currently linear, but this adds span support when we implement 1D tiling. This fixes the text in progs/demos/engine and progs/tests/z*
