i965/fs: Try to emit LINE instructions on Gen <= 5.
The LINE instruction performs a multiply-add instruction (a * b + c)
where b and c are scalar arguments. It reads b and c from offsets in
src0 such that you can load them (it they're representable) as a
vector-float immediate with a single instruction.
Hurts some programs, but that'll all get better once we CSE the
vector-float MOVs in the next patch.
