[965] Fix inversion of SLT/SGE results in vertex programs.
The WM code had this right, so copy its behavior. This reverts a flipping of the arguments to SLT in brw_vs_tnl which came in with the GLSL code that probably occurred to work around the flipped results, and brings the code back in line with t_vp_build.c.
