Robert Clausecker d8385768fb lib/libc/amd64/string/strlen.S: add amd64 baseline kernel 
This performs very well.  x86-64-v3 and x86-64-v4 kernels were written,
too, but performed worse than the baseline kernel on short strings.
These may be added at a future point in time if the performance issues
can be fixed.
