Well, compiling both makes testing and comparison benchmarks easier and allows
runtime-switching if we want to support devices where which one is faster
might depend on which CPU extensions are available.
I don't mind much either way, it just seemed like the more flexible solution,
particularly since I don't know the speed difference between both.
