Convert SHA-1 SSSE3 implementation from mixed asm&C to pure asm

* cipher/Makefile.am: Change 'sha1-ssse3-amd64.c' to
'sha1-ssse3-amd64.S'.
* cipher/sha1-ssse3-amd64.c: Remove.
* cipher/sha1-ssse3-amd64.S: New.

Mixed C&asm implementation appears to trigger GCC bugs easily. Therefore
convert SSSE3 implementation to pure assembly for safety.

Benchmark also show smallish speed improvement.

Intel i5-4570 5.22 c/B 5.09 c/B
Intel i5-2450M 7.24 c/B 7.00 c/B
