\brief Retrieve the value of an Integral TemplateArgument (of a function decl representing a template specialization) as a signed long long.
It is undefined to call this function on a CXCursor that does not represent a FunctionDecl or whose I'th template argument is not an integral value.
For example, for the following declaration and specialization: template <typename T, int kInt, bool kBool> void foo() { ... }
template <> void foo<float, -7, true>();
If called with I = 1 or 2, -7 or true will be returned, respectively. For I == 0, this function's behavior is undefined.
