SHA-512: Add SSSE3 implementation for x86-64
* cipher/Makefile.am: Add 'sha512-ssse3-amd64.S'.
* cipher/sha512-ssse3-amd64.S: New.
* cipher/sha512.c (USE_SSSE3): New.
(SHA512_CONTEXT) [USE_SSSE3]: Add 'use_ssse3'.
(sha512_init, sha384_init) [USE_SSSE3]: Initialize 'use_ssse3'.
[USE_SSSE3] (_gcry_sha512_transform_amd64_ssse3): New.
(transform) [USE_SSSE3]: Call SSSE3 implementation.
* configure.ac (sha512): Add 'sha512-ssse3-amd64.lo'.

Patch adds fast SSSE3 implementation of SHA-512 by Intel Corporation. The
assembly source is licensed under 3-clause BSD license, thus compatible
with LGPL2.1+. Original source can be accessed at:
http://www.intel.com/p/en_US/embedded/hwsw/technology/packet-processing#docs
Implementation is described in white paper
"Fast SHA512 Implementations on Intel® Architecture Processors"
