Add OCB bulk mode for AES SSSE3 implementation
* cipher/rijndael-ssse3-amd64.c (SSSE3_STATE_SIZE): New.
[HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS] (vpaes_ssse3_prepare): Use
'ssse3_state' for storing current SSSE3 state.
[HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS]
(vpaes_ssse3_cleanup): Restore SSSE3 state from 'ssse3_state'.
(_gcry_aes_ssse3_do_setkey, _gcry_aes_ssse3_prepare_decryption)
(_gcry_aes_ssse3_encrypt, _gcry_aes_ssse3_cfb_enc)
(_gcry_aes_ssse3_cbc_enc, _gcry_aes_ssse3_ctr_enc)
(_gcry_aes_ssse3_decrypt, _gcry_aes_ssse3_cfb_dec)
(_gcry_aes_ssse3_cbc_dec, _gcry_aes_ssse3_cbc_dec): Add 'ssse3_state'
array.
(get_l, ssse3_ocb_enc, ssse3_ocb_dec, _gcry_aes_ssse3_ocb_crypt)
(_gcry_aes_ssse3_ocb_auth): New.
* cipher/rijndael.c (_gcry_aes_ssse3_ocb_crypt)
(_gcry_aes_ssse3_ocb_auth): New.
(_gcry_aes_ocb_crypt, _gcry_aes_ocb_auth) [USE_SSSE3]: Use SSSE3
implementation for OCB.
