…ldAttributeSubSection::Name BuildAttributeSubSection::Name must be a std::string instead of StringRef because it may be assigned from non-persistent memory. StringRef is non-owning and unsafe in this context. This change ensures the subsection name owns its memory, preventing use-after-free or dangling references. Context: Work in progress in PR llvm#131990.
