That would be nice, but I looked into it a bit and it won't work. This is just
several layers of wrappers around an llvm::SymbolTableList, which is in turn a
couple of wrappers around llvm::simple_list, which uses a sentinel value for
its end iterator. If I try to pass null for insertPoint, it crashes in
`llvm::ilist_base<true, void>::insertBeforeImpl()`.
