r177003 applied the late parsed template technique to friend functions
but omitted the corresponding check for redefinitions.
This patch adds the same check already in use for templates to the
new code path in order to diagnose and reject invalid redefinitions
that were being silently accepted.
Fixes PR17324.

- 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.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

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>.
