sna/gen4: Use the special composite rect emission for fill_one()
    
    In order to workaround a bug in the shaders on gen4, we need to flush
    the pipeline after every rectangle. The recently introduced fill-one
    mechanism for gen4, missed this vital step triggering a random hang with
    an otherwise sane batchbuffer (the missing flush is hard to spot!).
    
    Fixes regression from 86f99379ee5 (sna/gen4: Add fill-one).

Nice, but is there a patch for that I can submit to gentoo developpers ?

I hope they would be able to handle git commit ids, but you can also use
http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=a5353a7c1d1f02b887f61f543c8e4bd4e8bd104f
