Log:
        PR c++/87145 - bogus error converting class type in template arg list.
        * pt.c (convert_nontype_argument): Don't call
        build_converted_constant_expr if it could involve calling a conversion
        function with a instantiation-dependent constructor as its argument.

        * g++.dg/cpp0x/constexpr-conv3.C: New test.
        * g++.dg/cpp0x/constexpr-conv4.C: New test.
