[Mesa-dev] [PATCH] r600/sb: update last_cf for finalize if.

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

As Glenn did for finalize_loop we need to update_cf when we
add a POP at the end of a shader.

I think this fixes one of the earlier shader going off end
of memory problems we've stopped.
