i965/vs: Fix textureGrad() with shadow samplers on Haswell.
The shadow comparitor needs to be loaded into the Z component of the
last DWord.
Fixes es3conform's shadow_execution_vert and oglconform's
shadow-grad advanced.textureGrad.1D tests on Haswell.
NOTE: This is a candidate for stable branches.
