This doesn't have anything to do with libdecnumber, it's about how
std::decimal::decimalxx are defined in libstdc++.

Instead of an ICE with a nice message it would be more appropriate to issue a
warning (error?) that GCC can't pass the class the same as the associated
scalar type as required by the ABI, and don't set TYPE_TRANSPARENT_AGGR.
