Douglas Gregor 3a88c1d784 Improve the internal representation and semantic analysis of friend
function templates.

This commit ensures that friend function templates are constructed as
FunctionTemplateDecls rather than partial FunctionDecls (as they
previously were). It then implements template instantiation for friend
function templates, injecting the friend function template only when
no previous declaration exists at the time of instantiation. 

Oh, and make sure that explicit specialization declarations are not
friends.

Douglas Gregor 7f34baeb4b When declaring a friend class template, we may end up finding an
injected-class-name (e.g., when we're referring to other
specializations of the current class template). Make sure that we see
the template rather than the injected-class-name. Fixes PR4768.

Douglas Gregor 3dad842b35 Rework the Parse-Sema interaction for friends to better support friend
class templates. We now treat friend class templates much more like
normal class templates, except that they still get special name lookup
rules. Fixes PR5057 and eliminates a bunch of spurious diagnostics in
<iostream>.
