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.

Extend libclang with a new cursor kind that indicates a reference to a

types such as vector<int>. Note that we do not handle the

within a template.

Implement basic support for indexing function templates in
libclang. This includes:
- Cursor kind for function templates, with visitation logic
- Cursor kinds for template parameters, with visitation logic
- Visitation logic for template specialization types, qualified type
locations
- USR generation for function templates, template specialization
types, template parameter types.
Also happens to fix PR7804, which I tripped across while testing.

When instantiating a function type, instantiate the return type before
instantiating the parameters. In a perfect world, this wouldn't
matter, and compilers are free to instantiate in any order they
want. However, every other compiler seems to instantiate the return
type first, and some code (in this case, Boost.Polygon) depends on
this and SFINAE to avoid instantiating something that shouldn't be
instantiated.
We could fight this battle, and insist that Clang is allowed to do
what it does, but it's not beneficial: it's more predictable to
instantiate this way, in source order. When we implement
late-specified return types, we'll need to instantiate the return type
last when it was late-specified, hence the FIXME.

Improve code completion for initializer lists in constructors. Instead
of prioritizing just by initialization order, we bump the priority of

we'll still get ordered completion for the rest.
