iris: Add support for flushing the blitter (hackily)
To flush the blitter, we need to use MI_FLUSH_DW rather than the usual
PIPE_CONTROL we use on the 3D engine. Most of our code is set up to
suggest flushes via PIPE_CONTROL commands, however, so we hackily just
emit MI_FLUSH_DW when they ask for any kind of PIPE_CONTROL flush.
