Unfortunaltely I still haven't managed to figure out why chrome
becomes a bit hangy on my ivb when I start to emit
3DSTATE_CONSTANT_* in the ddx.
The error state is somewhat peculiar BTW. It always hangs at the
start of a batch like so:
ACTHD: 0x00000000 00efa014
batch (rcs0 (submitted by chrome [23031], ctx 2 [5], score 0)) at 0x00000000_00efa000

No idea why there's an end of pipe flush as the first thing in the batch,
and no idea how that could possibly hang due to stuff that was done in
another batch/context.
