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.
