    u_tile: fix stencil texturing tests under softpipe

    arb_stencil_texturing-draw failed under softpipe because we got a float
    back from the texturing function, and then tried to U2F it, stencil
    texturing returns ints, so we should fix the tiling to retrieve
    the stencil values as integers not floats.
