  avutil/x86/aes: remove a few branches
  
  The rounds value is constant and can be one of three hardcoded values, so
  instead of checking it on every loop, just split the function into three
  different implementations for each value.
  
  Before:
  aes_decrypt_128_aesni:                                  93.8 (47.58x)
  aes_decrypt_192_aesni:                                 106.9 (49.30x)
  aes_decrypt_256_aesni:                                 109.8 (56.50x)
  aes_encrypt_128_aesni:                                  93.2 (47.70x)
  aes_encrypt_192_aesni:                                 111.1 (48.36x)
  aes_encrypt_256_aesni:                                 113.6 (56.27x)
  
  After:
  aes_decrypt_128_aesni:                                  71.5 (63.31x)
  aes_decrypt_192_aesni:                                  96.8 (55.64x)
  aes_decrypt_256_aesni:                                 106.1 (58.51x)
  aes_encrypt_128_aesni:                                  81.3 (55.92x)
  aes_encrypt_192_aesni:                                  91.2 (59.78x)
  aes_encrypt_256_aesni:                                 109.0 (58.26x)

  This saves on some VRAM, but mainly allows for a more unified path.

  avcodec/vorbisdec: Dont treat overread as error
  
  This differs from libvorbis by
  stddev:    2.44 PSNR: 88.58 MAXDIFF:   41 bytes:   834304/   834304
  for the file from the ticket
  
  Fixes: Ticket11427
  
  Regression since: dc89cf804a811c0d25f4649a99f7fab4b5b416fa
