I think this logic should be flipped around... you should have a flag
'lower_sub' which is false for vc4 but true for i965, and then if the
flag is true we lower sub to add+neg and if false we try and
reconstruct sub (and do other things like pulling neg's out of
multiplies). That way, eventually w
