Wennborg! Fixes PR8295.

clang_getDeclObjCTypeEncoding(); use ASTContext's methods instead,
which will (lazily) create the type as needed. Otherwise, we can end
up with null QualTypes.

implementation used by overload resolution to support rvalue
references. The original commits caused PR9026 and some
hard-to-reproduce self-host breakage.

The only (crucial!) difference between this commit and the previous
commits is that we now properly check the SuppressUserConversions flag
before attempting to perform a second user-defined conversion in
reference binding, breaking the infinite recursion chain of
user-defined conversions.

Rvalue references should be working a bit better now.

Check whether DependentScopeDeclRefExpr's NestedNameSpecifier exists before accessing it, both for consistency (see StmtPrinter::VisitDeclRefExpr()) and for other use cases of dependent types.

Mark VTables and RTTI data linkonce_odr instead of weak_odr, with the exception of explicit template instantiations, which have to be weak_odr.

This fixes PR6996.

  error: no super class declared in @interface for 'XXX'

to be:

  error: 'X' cannot use 'super' because it is a root class

The latter explains what the user actually did wrong.

clang's -Wuninitialized-experimental warning.
While these don't look like real bugs, clang's
-Wuninitialized-experimental analysis is stricter
than GCC's, and these fixes have the benefit
of being general nice cleanups.

Accept the C++0x override control keywords as an extension in C++98. This is OK since the new syntax is unambiguous and can't be confused with C++98 syntax. If anyone disagrees, please shout!
