[boost] [phoenix] Bind member functions with non-const reference parameters

Using phoenix bind with member functions that have non-const reference
parameters results in compile errors. However, free functions with
similar signature seem to be supported. This behavior is inconsistent,
especially compared to existing bind incarnations. For instance:

#include <boost/bind.hpp>
#include <boost/lambda/bind.hpp>
#include <boost/phoenix/phoenix.hpp>

void foo(int&) { }

struct Foo
{
    void bar(int&) { }
};

int main()
{
    using boost::phoenix::placeholders::arg1;

    int i = 0;
    Foo f;

    boost::phoenix::bind(foo, arg1)(i); // works
    boost::lambda::bind(&Foo::bar, &f, boost::lambda::_1)(i); // works
    boost::bind(&Foo::bar, &f, _1)(i); // works
    boost::phoenix::bind(&Foo::bar, &f, arg1)(i); // compile error
}

Tested with VC10 and boost trunk (r72541).
