but it didn't work out.  I'm afraid we need to actually implement properly the
OpenMP 5.0 automatic omp declare target discovery and before IPA run perhaps
another iteration of that and make sure that if we offload something, we either
offload everything it refers to too (unless DECL_EXTERNAL), or diagnose it.
