It might help if you could explain what you are *actually* trying to do, since there are often other solutions for the higher-level problem that fit better into the design and architecture.

As an example, say I have a DICompositeType describing a struct. Now I want to find other DITypes containing this type, e.g. a DIDerivedType describing its pointer type, or another struct containing this struct as one of its fields. Is this possible in LLVM today? Would it be unreasonable to save Metadata to Metadata uses, like what is done for Value to Value uses?
