i965/vec4: Do not use DepCtrl with 64-bit instructions

The BDW PRM says that it is not supported, but it seems that gen7 is also
affected, since doing DepCtrl on double-float instructions leads to
GPU hangs in some cases, which is probably not surprising knowing that
this is not supported in new hardware iterations. The SKL PRMs do not
mention this restriction, so it is probably fine.
