Add support for MSVC 2015 

MSVC 2015 has a partial support for C++14, and in particular for C++14
`constexpr` functions. Since Boost-1.57 (that is the minimal
requirement for CGAL since version 5.0), `<boost/config.hpp>` has a
macro `BOOST_CXX14_CONSTEXPR` that can be either `constexpr` for
fully-C++14 compilers, or empty for non-compliant compilers.
