rinjdael: add amd64 assembly implementation
* cipher/Makefile.am: Add 'rijndael-amd64.S'.
* cipher/rijndael-amd64.S: New file.
* cipher/rijndael.c (USE_AMD64_ASM): New macro.
[USE_AMD64_ASM] (_gcry_aes_amd64_encrypt_block)
(_gcry_aes_amd64_decrypt_block): New prototypes.
(do_encrypt_aligned) [USE_AMD64_ASM]: Use amd64 assembly function.
(do_encrypt): Disable input/output alignment when USE_AMD64_ASM is set.
(do_decrypt_aligned) [USE_AMD64_ASM]: Use amd64 assembly function.
(do_decrypt): Disable input/output alignment when USE_AMD64_AES is set.
* configure.ac (aes) [x86-64]: Add 'rijndael-amd64.lo'.
