> So far strings are not subject to IPA scalar propagation into functions (and
> the determination if it would be safe to do so). However, there are a number
> of functions that pass parameters like "train" / "eval" used in branches. If
> we would propagate consistent scalars into this functions, we can fold these
> constant predicates, removal unnecessary branches, and finally inline
> single-block functions into the caller.
