batch: Ensure we send a MI_FLUSH in the block handler for TFP

This should restore the previous level of synchronisation between
textures and pixmaps, but *does not* guarantee that a texture will be
flushed before use. tfp should be fixed so that the ddx can submit the
batch if required to flush the pixmap.

A side-effect of this patch is to rename intel_batch_flush() to
intel_batch_submit() to reduce the confusion of executing a batch buffer
with that of emitting a MI_FLUSH.

Should fix the remaining rendering corruption involving tfp [inc compiz]:
