Summary: We currently have a bunch of code that is supposed to handle invalid command options, but all this code is unreachable because invalid options are already handled in `Options::Parse`. The only way we can reach this code is when we declare but then not implement an option (which will be made impossible with D65386, which is also when we can completely remove the `default` cases). This patch replaces all this code with `llvm_unreachable` to make clear this is dead code that can't be reached.
