Change auto_max_partition behaviors on speed 6

This CL changes auto_max_partition_based_on_simple_search to direct
prediction on midres, and disables it on hdres.

Performance:
 TESTSET | AVG_PSNR | OVR_PSNR |   SSIM  |  SPD
   HDRES |  -0.011% |  -0.010% | -0.010% | +0.9%
  MIDRES |  +0.075% |  +0.074% | +0.075% | +0.7%
