The original implementation uses `ND->getFormalLinkage() <= Linkage::InternalLinkage`. It is not right since the spec only says internal linkage and it doesn't mention 'no linkage'. This matters when we consider constructors. According to [class.ctor.general]p1, constructors have no name so constructors have no linkage too.
