[Beignet] Haswell-ULT Support?

[Julian Simioni]

Ok, that didn't have a very surprising result. I simply confirmed that
f0a346b is the commit that breaks things. However I can confirm again
that c9224f does NOT fix things on its own, only disabling the command
parser does the trick. I'm happy to test any patches you think can fix
this, but at least thanks for pointing me back to the echo 0 ... trick
that I had skipped over.
