The assembly loops are enabled automatically on x86, unless you turn 
them off with --disable-x86-asm.

Assembly versions are used for the most important loops (_sse on 
Pentium and Athlon XP, _3dnow on old Athlons), but there are a couple 
of cases (like buckingham) where we have to use C loops instead.
