Chris Wilson 4b7bbb2a23 sna: Only flush before adding fresh surfaces to the batch 
Previously, before every operation we would look to see if the GPU was
idle and we were running under a DRI compositor. If the GPU was idle, we
would flush the batch in the hope that we reduce the cost of the context
switch and copy from the compositor (by completing the work earlier).
However, we would complete the work far too earlier and as a result
would need to flush the batch before every single operation resulting in
extra overhead and reduced performance. For example, the gtkperf
circles benchmark under gnome-shell/compiz would be 2x slower on
Ivybridge.
