    Compared against baseline with default enabled tools (except for
    ext-tx and global-motion for speed concern):
    
                     altref2 -> altref2 + flex-refs
    lowres: avg_psnr -0.395% -> -0.460%
    midres: avg_psnr -0.418% -> -0.478%
    
    In particular, flex-refs improves the coding performance for the
    following 3 clips while no impact on all other clips:
    
    bowing_cif.y4m:    avg_psnr  0.023% -> -1.022%
    pamphlet_cif.y4m:  avg_psnr  0.454% -> -1.111%
    snow_mnt_480p.y4m: avg_psnr -0.162% -> -1.948%
