LLVM IR emitted in our C++ codebase contains `@llvm.global_ctors = appending global [0 x { i32, ptr, ptr }] zeroinitializer`, I could go dig clang codegen to find out why this gets emitted but it feels orthogonal here - seems rather silly that if try to roundtrip code like this from the importer, we'll end up with nothing in place.

If you think this should be represented differently (i.e. not by empty lists), please let me know what approach you'd like to see.
