`-force-attribute` needs a function name, like ` -force-attribute=foo:use-sample-profile`, so it is unfeasible to apply it to every function in the IR. Although it is quite easy to add support for wildcard like ` -force-attribute=*:use-sample-profile` and I think this sounds like an elegant solution
