SHA-1/SSSE3: Improve performance on large buffers
* cipher/sha1-ssse3-amd64.S (RNBLKS): New.
(_gcry_sha1_transform_amd64_ssse3): Handle multiple input blocks, with
software pipelining of next data block processing.
* cipher/sha1.c [USE_SSSE3] (_gcry_sha1_transform_amd64_ssse3): Add
'nblks'.
(transform) [USE_SSSE3]: Pass nblks to assembly function.
