i965: Set the region of LINE's src0 to <0,1,0>.

The PRMs say that

   <src0> region must be a replicated scalar
   (with HorzStride = VertStride = 0).

but apparently that doesn't actually apply to all generations. I did
notice when implementing the optimization later in this series that G45
and ILK needed this regioning.
