64-bit support for integer_traits on MSVC

It seems that there should be a way to get 64-bit integer support into
integer_traits.hpp on MSVC.  It looks like the only real problem is the
missing feature of class constants, and the fact that integer_traits is
using enums (which can't hold const_max and const_min values).

But if there were specializations on the detail::integer_traits_base for MS
64-bit types, the constants could be declared in-class as __int64 but
defined out-of-class (still in the header), safely.  It's not as pretty as
BOOST_STATIC_CONSTANT, but wouldn't it work?
