void intel_frontbuffer_flush (

frontbuffer plane tracking bits
which operation caused the flush
This function gets called every time rendering on the given planes has
completed and frontbuffer caching can be started again. Flushes will get
delayed if they're blocked by some outstanding asynchronous rendering.
Can be called without any locks held.
