  Changed paths:
    M llvm/lib/ObjCopy/ELF/ELFObject.cpp
    M llvm/lib/ObjCopy/ELF/ELFObject.h
    M llvm/test/tools/llvm-objcopy/ELF/remove-section-in-group.test

  Log Message:
  -----------
  [llvm-objcopy] Remove references for empty section groups (#98106)

Otherwise, llvm-objcopy fails with use-after-free when built under
sanitizers. Simple repro: run the test
`ELF/remove-section-in-group.test` under asan. This is due to symbol
table references to empty section groups that must be removed.
