I did so now. I've attached a patch for all of: MD5, MD4, SHA-1.

I was wrong about that - somehow I did not notice the even better speed
for MD5-crypt there. I got it now:
Benchmarking: FreeBSD MD5 [SSE2i 8x]... (8xOMP) DONE
Raw: 203013 c/s real, 25426 c/s virtual
Now this is significantly better than Core i7-2600, which IIRC only
gives under 160k on this test. (Both CPUs benchmarked at stock clocks.)
And here's what I am getting for the raw hashes. With -x86-64i (Intel
compiler's SSE2 code):
Benchmarking: Raw MD5 [SSE2i 12x]... DONE
Raw: 32896K c/s real, 32682K c/s virtual
Benchmarking: Raw MD4 [SSE2i 12x]... DONE
Raw: 37282K c/s real, 37282K c/s virtual
Benchmarking: Raw SHA-1 [SSE2i 8x]... DONE
Raw: 18236K c/s real, 18236K c/s virtual
With -x86-64 (gcc's SSE2 code):
Benchmarking: Raw MD5 [SSE2i 12x]... DONE
Raw: 24432K c/s real, 24197K c/s virtual
Benchmarking: Raw MD4 [SSE2i 12x]... DONE
Raw: 34473K c/s real, 34473K c/s virtual
Benchmarking: Raw SHA-1 [SSE2i 8x]... DONE
Raw: 17567K c/s real, 17567K c/s virtual
With -x86-64-avx:
Benchmarking: Raw MD5 [SSE2i 12x]... DONE
Raw: 23301K c/s real, 23087K c/s virtual
Benchmarking: Raw MD4 [SSE2i 12x]... DONE
Raw: 35444K c/s real, 35696K c/s virtual
Benchmarking: Raw SHA-1 [SSE2i 8x]... DONE
Raw: 19284K c/s real, 19284K c/s virtual
Finally, the improvement with -x86-64-xop (due to this patch):
Benchmarking: Raw MD5 [SSE2i 8x]... DONE
Raw: 32577K c/s real, 32577K c/s virtual
Benchmarking: Raw MD4 [SSE2i 8x]... DONE
Raw: 36872K c/s real, 36872K c/s virtual
Benchmarking: Raw SHA-1 [SSE2i 8x]... DONE
Raw: 23464K c/s real, 23464K c/s virtual
So raw MD5 and raw MD4 are similar to Intel compiler code's speed,
whereas raw SHA-1 is now 28% faster than Intel's and 21% faster than AVX.
