I agree with @dblaikie here, I can't come up with a scenario where this would be required. Unless like he mentioned we emit all the function declarations, which we don't.

@probinson I was reading the C++ "auto" return type <http://dwarfstd.org/ShowIssue.php?issue=131217.1> issue and I can't come up with a case where we don't have class descriptions across compilation units that are not consistent wrt to auto return type. Do you have a specific example?
