I don't made any test on autogame only compare both code in outside 
separate tree. (here it is much faster)

When you want full autogame test you need savegame code. I don't made 
it becouse I'm not sure that it is need. ( I little misunderstand 
reason of this part ).

Yes I know but this can be fixed in 2 way.

1) fix current code. ( see comments on 
http://burtleburtle.net/bob/rand/isaacafa.html )
2) use other 64 bit version for this platform ( detect code )
