I don't think there is a way to do this without modifying gcc. FWIW,
I think that would be a worthwhile project; IMO gcc should move a bit
more into the analysis space.

Note that the C front end does lose information relatively early. For
instance, it constant folds as it builds expression trees. So, even
internally the AST won't show you some things that you might want to
see. This is also fixable of course.
