The Impact Of GCC Zen Compiler Tuning On AMD Ryzen Performance

With the FFTW benchmark when going from just a generic -O3 optimized build to using znver1, the performance improved by about 6%.

With the HMMer scientific workload, the builds with these additional instruction set extensions hadn't ended up making any real difference on performance.

A bit strange, for SciMark2 when using the Bulldozer compiler -march=, the performance had improved a tiny bit, but when using znver1 the performance was unchanged.

SciMark's FFT performance had regressed with the CPU tuning.
