Die

std::atomic<DIE *> llvm::dwarf_linker::parallel::TypeEntryBody::Die = {nullptr}

TypeEntryBody keeps partially cloned DIEs corresponding to this type.

The two kinds of DIE can be kept: declaration and definition. If definition DIE was met while parsing input DWARF then this DIE would be used as a final DIE for this type. If definition DIE is not met then declaration DIE would be used as a final DIE.
