    d: Only handle named enums in enum_initializer_decl
    
    Anonymous enums neither generate an initializer nor typeinfo symbol, so
    it's safe to assert that all enum declarations passed to this function
    always have an identifier.
    
    gcc/d/ChangeLog:
    
            * decl.cc (enum_initializer_decl): Only handle named enums.
