Improve handling of friend types in several ways:
- When instantiating a friend type template, perform semantic
analysis on the resulting type.
- Downgrade the errors concerning friend type declarations that do
not refer to classes to ExtWarns in C++98/03. C++0x allows
practically any type to be befriended, and ignores the friend
declaration if the type is not a class.
