Add a new libclang function clang_getTemplateCursorKind(), which

determines the kind of declaration that would be generated if the
given template were instantiated. This allows a client to distinguish
among class/struct/union templates and function/member function/static
member function templates.

Also, teach clang_CXXMethod_isStatic() about function templates.
