Changed GenerateConstantString() to take an ObjCStringLiteral (instead of a std::string). While this isn't strictly necessary, it seems cleaner and allows us to cache to "containsNonAscii" if necessary (to avoid checking in both Sema and CodeGen).

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

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.

representation handles the various ways in which one can name a
template, including unqualified references ("vector"), qualified
references ("std::vector"), and dependent template names
("MetaFun::template apply").

One immediate effect of this change is that the representation of
nested-name-specifiers in type names for class template
specializations (e.g., std::vector<int>) is more accurate. Rather than
representing std::vector<int> as

  std::(vector<int>)

we represent it as

  (std::vector)<int>

which more closely follows the C++ grammar. 

Additionally, templates are no longer represented as declarations
(DeclPtrTy) in Parse-Sema interactions. Instead, I've introduced a new
OpaquePtr type (TemplateTy) that holds the representation of a
TemplateName. This will simplify the handling of dependent
template-names, once we get there.
