In an instruction sequence like
cmp(8).ge.f0.0 vgrf17:D, vgrf2.xxxx:D, vgrf9.xxxx:D
(+f0.0) sel(8) vgrf1:UD, vgrf8.xyzw:UD, vgrf1.xyzw:UD
The other fields of vgrf17 may be unused, but the CMP still needs to
generate the other flag bits.
To my surprise, nothing in shader-db or any test suite appears to hit
this. However, I have a change to brw_vec4_cmod_propagation that
creates cases where this can happen. This fix prevents a couple dozen
regressions in that patch.
