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
