CFLAGS are compiler options, and thus must be distribution-agnostic. Try those
in Arch, of course, but name package like -opimized, so it will be clear even
after some time what exactly you have installed.
Do your usual work, including all those effect and most importantly final
rendering (I haven't tested this step!). If after some playing results are
visually (or numerically - if you care about it enough) identical to standard
build, but faster (and Cin doesn't crash on you more often/in unusual ways) -
you can keep those flags.
You also can try to enable ONLY auto-vectorization with -O2 level of generic
