Not many places rely on this assumption that you can order SourceLocations,
because that only works when they have the same FileID.
Formally, this could be composed from token from different files, even if it's
not in any way common practice.
I think we should be able to quickly tell where the end location is supposed to
come from, based on the kind of template is being instantiated.
