I don't know much about compiling. I successfully use pacaur and set my compiler flags. I came across pgo,lto and bolt the other day and was wondering if there is a way to implement lto, pgo and/or bolt somewhat comfortably.
Maybe if its cumbersome, it would be worth it to compile chromium/firefox and the kernel with those cache optimizers.

makepkg enables LTO by putting this in the PKGBUILD:
options=('lto')

I thought chromium and firefox were already built with LTO and PGO? The kernel supports LTO but only if you build it with clang.
Edit:
Do be careful when setting such options through compiler flags see for example https://bbs.archlinux.org/viewtopic.php?id=269172
