i965: Don't emit SURFACE_STATEs for gather workarounds on Broadwell.
As far as I can tell, Broadwell doesn't need any of the SURFACE_STATE
workarounds for textureGather() bugs, so there's no need to emit
a second set of identical copies.
To keep things simple, just point the gather surface index base to the
same place as the texture surface index base.
