We could limit this debug info for  DW_TAG_enumerator and DW_TAG_enumeration_type for unnamed decls for FullDebugInfo mode only ?

I'd rather find a way to fix this even in -flimit-debug-info mode -
because it'll still be a bug/confusing to get different behavior based
on named/unnamed-ness of a type...

but I haven't had time to look around and see how we might achieve
that. Perhaps there's some other hook or data structure we can use to
find these decls (where/how do enums end up in DeferredDecls - if we
look around there can we find an entry point that handles both named
and unnamed equally)

do issues like this affect unnamed types of other kinds
(struct/class/union) too? I assume not, but just asking/checkin.
