i965: Respect the no_8 flag on Gen6, not just Gen7+.
When doing repclears, we only want to use the SIMD16 program, not the
SIMD8 one. Kristian added this to the Gen7+ code, but apparently we
missed it in the Gen6 code. This patch copies that code over.
Approximately doubles the performance in a clear microbenchmark from
mesa-demos (clearspd -width 500 -height 500 +color) on Sandybridge.
