My reading of the LLVM language reference leads me to believe it’s only ordered
per-module. If that’s the case, the benefit of emitting into `XC*` is that it
provides guaranteed order over all linker input.
`llvm.global_ctors` excerpt:

Now if the priority system _is_ guaranteed over all linker input, will that
guarantee hold for mixed Clang and CL objects?
