Add skip_related_full_newmv speed feature

This CL introduces a new speed feature that prunes the current
ref_mv in NEW_MV mode after a full_pixel search if we have already
encountered another ref_mv in the drl such that:
 1. The other drl has the same fullpel_mv during the SIMPLE_TRANSLATION
    search process as the current fullpel_mv.
 2. The rate needed to encode the current fullpel_mv is larger than that
    for the other ref_mv.

This is turned on on speed 3 and above.

Performance on midres:
  SPD_SET | AVG_PSNR | OVR_PSNR |   SSIM  |  SPD  |
     3    |  +0.150% |  +0.157% | +0.084% | +3.8% |
     4    |  +0.129% |  +0.133% | +0.114% | +3.6% |
     5    |  +0.120% |  +0.128% | +0.135% | +3.1% |
