Ok with preserving options as dummy, see examples like

Does nothing. Preserved for backward compatibility.
I don't think we should sorry (), but we can certainly warn that
mudflap was replaced by -fsanitize=address(?). Implementing
the warning properly isn't a requirement for the patch to go in
(but the options should be still handled, but ignored). We can
followup with a patch implementing the warning.
Note that warning is just a matter of putting
Warn(switch %qs is no longer supported)
alongside Ignore - see various options in c.opt for examples.
Thanks. It turns out there's an example just after -fmudflapir :-)
