I think we want to have a whitelist of "clang options" that are distinct
from gcc options, rather than blacklisting a troublesome few (-MD) as
GCCOptions. That seemed to be the main conclusion of the discussion on
We obviously don't want to add Flags<[ClangOption]> to every option in
f_Group and f_clang_Group, so there'll have to be some tablegen magic in
Does that seem reasonable?
