GCC has the ability to perform auto-vectorization, but only does so at -O3 or when explicitly told to.

If we add a flag that tells GCC to perform auto-vectorization on specific functions, we can enabled it on those functions alone that would benifit from it, and thereby do not risk the potential binary bloat or performance degradation that can come from using -O3 indiscriminately.
