Douglas Gregor 205d044552 Switch diagnostic text from "C++0x" over to "C++11". 
We'd also like for "C++11" or "c++11" to be used for the warning
groups, but without removing the old warning flags. Patches welcome;
I've run out of time to work on this today.

Douglas Gregor 932aac6492 Tweak the diagnostics for the C++0x extensions to friend types to note 
that they are C++0x extensions, and put them in the appropriate
group. We already support most of the semantics. Addresses
<rdar://problem/9407525>.

Douglas Gregor 3b4abb6792 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.
