Well, as a first step, I'd replace all inline asm stuff with C/C++
implementations in the original version using MSVC.  Performance might
become worse than the original, or it might not.  Either way, I'd leave
those optimizations for later.  Moreover, it would give you a CPU
independent version of the code, which is often a good thing :)

A test_main with a bunch of assert checks should suffice as a start.
