i965/gen4: Fix LOD bias texturing since my fixed reg classes change.

We have a special case where non-shadow comparison with LOD requires using a
SIMD16 vec4 in an 8-wide shader, which appears in the register allocator as a
size 8 vgrf.

Fixes assertions in various piglit tests and webgl conformance.
