I don't know how far DWARFv5 is at the moment, these proposals haven't
even made it to a draft yet, so we might have to look at turning them
into GNU extensions first then.

But first I need some feedback on the dwarf2out.c refactoring for
passing around cv-qualifiers and the addition of the restrict tag
patches on which these DWARFv5 prototypes are based:
