blowfish: add amd64 assembly implementation
* cipher/Makefile.am: Add 'blowfish-amd64.S'.
* cipher/blowfish-amd64.S: New file.
* cipher/blowfish.c (USE_AMD64_ASM): New macro.
[USE_AMD64_ASM] (_gcry_blowfish_amd64_do_encrypt)
(_gcry_blowfish_amd64_encrypt_block)
(_gcry_blowfish_amd64_decrypt_block, _gcry_blowfish_amd64_ctr_enc)
(_gcry_blowfish_amd64_cbc_dec, _gcry_blowfish_amd64_cfb_dec): New
prototypes.
[USE_AMD64_ASM] (do_encrypt, do_encrypt_block, do_decrypt_block)
(encrypt_block, decrypt_block): New functions.
(_gcry_blowfish_ctr_enc, _gcry_blowfish_cbc_dec)
(_gcry_blowfish_cfb_dec, selftest_ctr, selftest_cbc, selftest_cfb): New
functions.
(selftest): Call new bulk selftests.
* cipher/cipher.c (gcry_cipher_open) [USE_BLOWFISH]: Register Blowfish
bulk functions for ctr-enc, cbc-dec and cfb-dec.
* configure.ac (blowfish) [x86_64]: Add 'blowfish-amd64.lo'.
* src/cipher.h (_gcry_blowfish_ctr_enc, _gcry_blowfish_cbc_dec)
(gcry_blowfish_cfb_dec): New prototypes.

Add non-parallel functions for small speed-up and 4-way parallel functions for
modes of operation that support parallel processing.
