i965: Actually upload sampler state pointers for the VS unit on Gen6.

We already program all the sampler state correctly, we just didn't give
the GPU a pointer to it for the VS stage.  Thus, any texturing other
than texelFetch() wouldn't work.

Fixes piglit test vs-textureLod-miplevels and 99 of oglconform's
glsl-bif-tex subtests.

NOTE: This is a candidate for the 8.0 branch.
