 - Large improvement on MSAC decoding with SSE, bringing 4-6% speed increase
   The impact is important on SSSE3, SSE4 and AVX-2 cpus
 - SSSE3 optimizations for all blocks size in itx
 - SSSE3 optimizations for ipred_paeth and ipref_cfl (420, 422 and 444)
 - Speed improvements on CDEF for SSE4 CPUs
 - NEON optimizations for SGR and loop filter
 - Minor crashes, improvements and build changes
