Always treat DISubprogram reached by DIImportedEntity as needed. It is illegal to have a null entity in a DIImportedEntity, so we must link in a DISubprogram metadata node referenced by one, even if the associated function is not linked in or inlined anywhere. Fixes PR26037. llvm-svn: 257000

[Linker] Also treat a DIImportedEntity scope DISubprogram as needed. Follow-up to r257000: DIImportedEntity can reach a DISubprogram via its entity, but also via its scope. Handle the latter case as well. PR26037. llvm-svn: 257019
