I remember some efforts to move out marking tail calls to a separate pass <https://reviews.llvm.org/D60031> so this should be cheaper to do marking once again (not sure to what extent). It was not landed earlier, but it was ready to land as I understand :)

Thanks for the pointer! I didn't know about that patch. I'll add a note about that to the commit message, so we can revive it if we decide it is worth saving some compile-time for a little extra code/specialization.
