i965/fs: Don't propagate saturation modifiers if there are source modifiers.

Which would lead to translating

   mad     vgrf9:F,  vgrf3:F, u0:F, vgrf6:F
   mov.sat vgrf7:F, -vgrf9:F

into

   mad.sat vgrf9:F,  vgrf3:F, u0:F, vgrf6:F
   mov     vgrf7:F, -vgrf9:F

Fixes some lighting effects in Dota2.
