Functionality is basically subsumed by IPSCCP (and the Attributor).
It is also not run by O3.

I don't know this pass very well, but may I ask, why isn't it used? I mean, is this transformation already implemented as part of another (used)?

As far as I know, the ipconstprop pass has not been actively used in years and ipsccp has been used instead. This has the potential for confusion and sometimes leads people to spend time finding & reporting bugs as well as updating it to work with the latest API changes. If there are people actively using it, I would love to hear. If no-ones using it, I’d propose to remove the dead code: https://reviews.llvm.org/D84447 +1 for removal
Cheers, Florian
