I've got a 4.4c/l , Agner Fog's says the thruput on 64 bit mul is 4c/l , but 
in another section it says you can issue one every cycle , if the latter 
section means 32bit then , 4c/l could be right ( I say could not would as 
consider the K8) , I expect I can do a bit better than 4.4c/l , but who 
knows.A lot of the speed comes from reducing the overhead in mul_basecase.

It quite a wide cpu , I would expect the combined functions(like addlsh1) to 
make a real difference on it.
