Driver: Add "d" flag to Options.def for options which are completely
handled by driver. - This is not very precise, we use it to drive the "forward-to-gcc" predicate, when trying to talk to a generic gcc tool. - Slightly better than what ccc was doing, and should be good enough. Platforms which want a robust driver should implement a proper tool chain. llvm-svn: 67181
