[PATCH] D104200: [lld-macho][nfc] Add `final` to classes where possible

[Noel Grandin via Phabricator via llvm-commits]

grandinj added a comment.

I did this (for LibreOffice), and final seems to be only a win when we do LTO and we can de-virtualise a bunch of stuff.

I was hoping that final would also help for dynamic_cast (where, in theory, if we're casting to a final type, we can optimise to a simple comparison), but that doesn't seem to be impemented by the dynamic_cast machinery (or the compiler)
