Well, I did not get it to 30M, but it is close. Best invocation:
Benchmarking: Raw SHA-1 [taviso sse4]... DONE
Raw: 29696K c/s real, 29696K c/s virtual
Worst:
Benchmarking: Raw SHA-1 [taviso sse4]... DONE
Raw: 28199K c/s real, 28199K c/s virtual
Patch attached. While at it, I also added a fix to sse-intrinsics.c for
32-bit builds with SSSE3.
