    For prediction block width equal to 32, avx2 can further speedup
    the prediction function (i7-6700):
    
    32x32     avx2 v. sse2
    DC        ~1.4x
    top       ~1.5x
    left      ~1.4x
    128       ~1.5x
    v         ~1.6x
    h         ~1.2x
    
    32x16     avx2 v. sse2
    DC        ~2.2x
    top       ~1.7x
    left      ~1.6x
    128       ~1.8x
    v         ~1.9x
    
    Note: 32x16 H_PRED on avx2 does not run faster enough than sse2 yet.
