[Mesa-dev] [RFC PATCH 10/14] anv: Add clflush to states.

[Rafael Antognolli]

TODO: This is just flushing the entire dynamic states on every execbuf.
Maybe it's too much. However, in theory we should be already flushing
the states as needed, but I think we didn't hit any bug due to the
coherence implied by userptr.
