[PATCH] D13221: Make CompilerInvocation's use of the debug options more understandable.

[Douglas Katzman via cfe-commits]

dougk added a comment.

I think the best thing to do is introduce new cc1 arguments that control the Opts explicitly, and cease accepting the equivalent driver arguments in cc1.
I would propose '-gdwarf-version={2|3|4}' and '-gdebug-info-kind={line-tables|limited|full}'
