    i965: Generate vs code using scalar backend for BDW+

    With everything in place, we can now use the scalar backend compiler for
    vertex shaders on BDW+.  We make scalar vertex shaders the default on
    BDW+ but add a new vec4vs debug option to force the vec4 backend.

    No piglit regressions.

    Performance impact is minimal, I see a ~1.5 improvement on the T-Rex
    GLBenchmark case, but in general it's in the noise.  Some of our
    internal synthetic, vs bounded benchmarks show great improvement, 20%-40%
    in some cases, but real-world cases are mostly unaffected.
