Or we can fix `pipe_slow()`to use reasonable `fixed_latency` instead of arbitrary 100.
It is used for float point instructions mostly and, I think, came from time when we used FPU instead of current SSE/AVX instructions.

But I think code in `output_h.cpp` should be fixed, as proposed, regardless what we do with `fixed_latency`.
