i965/vs: Use GRFs for pull constant offsets on gen7.
This allows the computation of the offset to get written directly into the
message source.
shader-db results:
total instructions in shared programs: 3308390 -> 3283025 (-0.77%)
instructions in affected programs: 442998 -> 417633 (-5.73%)
No difference in GLB2.7 low res (n=9).
