As @Mogball pointed out, this is indeed quite invasive. Sadly, I do also not know of any other way of supporting this, especially considering the subsequent extension for cyclic structures.
Considering that we would require the support for cyclic structures to fully support LLVM debug metadata import, landing this stack of commits would be very welcome.

What is the stance regarding this change from the people of the core team?
