glean depthStencil now fails but previously passed on softpipe.

$ glean -r results -t depthStencil --quick

    softpipe: do texture swizzle during texture sampling
    Instead of when we read texture tiles.  Now swizzling happens after
    the shadow depth compare step.  This fixes the piglit glsl-fs-shadow2d*
    tests (except for proj+bias because of a GLSL bug).
