REVISION SUMMARY
  This patch lets us view the size information when inspecting type
  aliases. E.g. for C++ code like the following, we'll now see the
  size (8) and alignment (also 8) when hovering Bar. Previously,
  that was only shown when hovering Foo:
  
    struct Foo { double m; };
    using Bar = Foo;
  
  Sadly, this patch by its own isn't yet enough for the more interesting
  cases, namely aliases of explicit template instantiations, such as
  
    using Ptr = std::shared_ptr<int>;
  
  Here, we still don't show any size information, since we don't track
  that information properly. In the builder, we only encounter std::shared_ptr
  as a template, which doesn't have any size information yet. We would
  need to build a declaration for the template instantiation of
  std::shared_ptr, at which point we could ask libclang for the concrete size...
  
  Still, this patch goes into the right direction already, I believe.
