[boost] [math] Support for libquadmath/ __float128

I have experimented with the quadmath library included with gcc and the boost::math::constants
library and encountered several problems.

- typeid is seemingly not supported for __float128, which requires an overload of nameof<__float128>
- the stream extraction operator has to be provided for __float128 for string conversion to work
- a specialisation of numeric_limits has to be provided.

Is there an interest in incorporating __float128 into boost ? If so, would it be a good idea to
specialise constants for __float128 as well, apart from float, double and long double?
