'identifier': explicit instantiation of function template requires return type

An explicit instantiation of a function template requires explicit specification of its return type. Implicit return type specification does not work.

The following sample generates C2909:

// C2909.cpp
// compile with: /c
template<class T> int f(T);
template f<int>(int);         // C2909
template int f<int>(int);   // OK
