[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.
