[PATCH] D58837: [ELF] Fix GCC8 warnings about "fall through", NFCI

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

`getDynamicTagAsString` is used by `llvm-objdump` and it'd be better if `llvm-objdump` can parse some malformed binaries (with bad `.dynsym`). If the tag is unknown, returning a stringified `Type` may make sense.
