Less with the talking, more with the benchmarking!

If what you say is true, then a sequence of add interleaved with 
lea should be faster than the equivalent sequence, but with add 
replacing the lea.  Benchmark code is here 
https://files.catbox.moe/2zzrwe.tar; on my system, the 
performance is identical.
