--- Comment #6 from Peter Collingbourne <peter at pcc.me.uk> ---
I ended up fixing this in r317108 by running EliminateAvailableExternally and
GlobalDCE at -O0 in ThinLTO backends.

It seems like a suboptimal fix to me, though. Offline, Reid mentioned a
potentially better fix, which would be to redesign how we represent filter
functions so that they become part of the parent function.
