[PATCH] D102479: [clang][driver] Treat unkonwn -flto= values as -flto

[Steven Wu via Phabricator via cfe-commits]

steven_wu added a comment.

I don't think current implementation is the best idea. I think is better to make the gcc compatible LTO value to be a clang Driver only option, give them an option name, and handle them separately in driver to invoke correct fullLTO cc1 command, so that:

- The value remain invalid option for cc1 (CompilerInvocation should just error on that, just like now).
- The ignored value should not appear in the help or autocompletion.
