fallback routines as i haven't managed to come up with any arm assembly that

actually can beat the c code (when compiled with all optimizations) in speed.

--enable-cpu-sse3

this enables sse3 optimizations available in the Intel Pentium4, Core, Xeon,

and Atom processors, as well as the AMD Athlon64, Phenom, Opteron, and Turion
|

processors.
