Testing
-------
Compared the benchmarks with and without the flags being used. Also did a
comparsion with the flags being used with and without optimizations and without
the flags being used with and without optimizations. Overall the performance
hit was very small with a 3-8% overhead (optimizations brings this down
slightly). Most benchmarks were about 5% (or less) slower.
