Can you please cherry-pick this commit to 17.3? It fixes GPU hangs.
Apparently there was not a Bugzilla, and I neglected to mark it with
Fixes or Cc (my mistake!). I haven't seen a huge number of affected
apps with this, so it likely doesn't warrant an emergency release or
anything...we'll just hit the next one. Thanks!

i965: Emit CS stall before MEDIA_VFE_STATE.
This fixes hangs on GFXBench 5's Aztec Ruins benchmark.
Unfortunately, it regresses OglCSCloth performance by about 10%. There
are some ideas for fixing that.
The Vulkan driver already emits this stall.
