example, the oft-mentioned

  typename MetaFun::template apply<T1, T2>::type

can now be instantiated, with the appropriate name lookup for "apply".

In a case like:

@class foo;
foo *P;

addRecordToClass was making an empty shadow struct for the foo interface and
completing it.  Later when an:

@interface foo
...
@endif

foo *Q;

was seen, ASTContext::addRecordToClass would think that foo was already laid
out and not lay out the definition.  This fixes it to create a forward declared
struct the first time around, then complete it when the definition is seen.

Note that this causes two tests to regress, because something is trying to get
the size of the forward declared structs returned by this.  Previously, this
would end up getting a size of zero but now it properly dies.  I'm not sure
what the right solution is for this, so I xfailed the tests.

Fariborz, please take a look at this.  The testcase in rdar://6676794 now gets
farther, but dies later because the objc ivar is not assigned a field number.

As an aside, I really don't like the fact that the objc front-end is creating
shadow C structs for ObjC types.  This seems like an implementation detail of
the code generator that could be fixed by better factoring of the extant code.

At present, we can't instantiate these nested-name-specifiers, so our
testing is sketchy.

Implement UCN support for C string literals (C99 6.4.3) and add some very basic tests. Chris Goller has graciously offered to write some test to help validate UCN support.

From a front-end perspective, I believe this code should work for ObjC @-strings. At the moment, I believe we need to tweak the code generation for @-strings (which doesn't appear to handle them). Will be investigating.

LHS type and the computation result type; this encodes information into 
the AST which is otherwise non-obvious.  Fix Sema to always come up with the 
right answer for both of these types.  Fix IRGen and the analyzer to 
account for these changes.  This fixes PR2601.  The approach is inspired 
by PR2601 comment 2.

Note that this changes real *= complex in CodeGen from a silent 
miscompilation to an explicit error.

I'm not really sure that the analyzer changes are correct, or how to 
test them... someone more familiar with the analyzer should check those 
changes.

instantiation for C++ typename-specifiers such as

  typename T::type

The parsing of typename-specifiers is relatively easy thanks to
annotation tokens. When we see the "typename", we parse the
typename-specifier and produce a typename annotation token. There are
only a few places where we need to handle this. We currently parse the
typename-specifier form that terminates in an identifier, but not the
simple-template-id form, e.g.,

  typename T::template apply<U, V>

Parsing of nested-name-specifiers has a similar problem, since at this
point we don't have any representation of a class template
specialization whose template-name is unknown.

Semantic analysis is only partially complete, with some support for
template instantiation that works for simple examples.
