[PATCH] D74006: [MC][ELF] Make linked-to symbol name part of ELFSectionKey

[Fangrui Song via Phabricator via llvm-commits]

================
Comment at: llvm/lib/MC/MCContext.cpp:320
   unsigned UniqueID = Section->getUniqueID();
   ELFUniquingMap.erase(
+      ELFSectionKey{Section->getSectionName(), GroupName, "", UniqueID});
----------------
As a note: this is only used by renaming `.debug_*` to `.zdebug_*`, which don't do SHF_LINK_ORDER magic. So using an empty linked-to symbol name will be fine.

As I understand it, `.zdebug*` are deprecated. ELF toolchain moves to SHF_COMPRESSED, so we don't need to add more support to `.zdebug*`.
