[PATCH] D69739: [llvm-objcopy][ELF] Add OriginalType & OriginalFlags

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

For some section types, we call their `classof` (via `isa` or `dyn_cast`) before mutation, so using either `OriginalType` or `Type` does not matter, e.g. DynamicSymbolTableSection, GroupSection. Some `classof` methods are unused, e.g. DynamicSection::classof.
