twofish: add amd64 assembly implementation
* cipher/Makefile.am: Add 'twofish-amd64.S'.
* cipher/twofish-amd64.S: New file.
* cipher/twofish.c (USE_AMD64_ASM): New macro.
[USE_AMD64_ASM] (_gcry_twofish_amd64_encrypt_block)
(_gcry_twofish_amd64_decrypt_block, _gcry_twofish_amd64_ctr_enc)
(_gcry_twofish_amd64_cbc_dec, _gcry_twofish_amd64_cfb_dec): New
prototypes.
[USE_AMD64_ASM] (do_twofish_encrypt, do_twofish_decrypt)
(twofish_encrypt, twofish_decrypt): New functions.
(_gcry_twofish_ctr_enc, _gcry_twofish_cbc_dec, _gcry_twofish_cfb_dec)
(selftest_ctr, selftest_cbc, selftest_cfb): New functions.
(selftest): Call new bulk selftests.
* cipher/cipher.c (gcry_cipher_open) [USE_TWOFISH]: Register Twofish
bulk functions for ctr-enc, cbc-dec and cfb-dec.
* configure.ac (twofish) [x86_64]: Add 'twofish-amd64.lo'.
* src/cipher.h (_gcry_twofish_ctr_enc, _gcry_twofish_cbc_dec)
(gcry_twofish_cfb_dec): New prototypes.
