6911,[Phoenix V3] Add tr1_result_of specialization,Michel Morin,Kohei Takahashi,"To make `result_of` and `tr1_result_of` equivalent, we have to add specialization of `tr1_result_of`. 
(Boost.Phoenix V3 already has specialization of `result_of`.)

Also, it would be nice to avoid specialization of `result_of`, when we use decltype-based `result_of`. 
(As for `tr1_result_of`, it should be specialized even when decltype-based `result_of` is used.)

So, instead of 
{{{
template <...>
struct result_of<F()>
{
    typedef XXXX type;
};
}}}
we should write
{{{
#if !defined(BOOST_RESULT_OF_USE_DECLTYPE) || defined(BOOST_NO_DECLTYPE)
template <...>
struct result_of<F()>
{
    typedef XXXX type;
};
#endif

template <...>
struct tr1_result_of<F()>
{
    typedef XXXX type;
};
}}}

A quick grep said the following files specialize `result_of`.
* phoenix/core/actor.hpp
* phoenix/function/function.hpp
