This is flat-out ill-formed (not implementation-defined). We're required to
reject this whether or not we actually perform copy-elision. See
[class.copy]p32: "This two-stage overload resolution must be performed
regardless of whether copy elision will occur. It determines the constructor to
be called if elision is not performed, and the selected constructor must be
accessible even if the call is elided."
