Daniel Dunbar 58e2971bb0 x86-32 Darwin ABI: Single element arrays can be part of "single
element structures", which have different ABI rules.
 - Current return-arguments-32 status is: 1 out of 1000 failures (-7)

 - Also, vectors inside "single element structs" require special
   handling.

Ted Kremenek 8b0dba358a Fix: <rdar://problem/6740387>. Sending nil to an object that returns a struct
should only be an error if that value is consumed. This fix was largely
accomplished by moving 'isConsumedExpr' back to ParentMap.

Chris Lattner 3088a31e96 remove ASTContext::buildObjCInterfaceType, which breaks canonical
types.  It is no longer needed now that the code generator 
re-lays-out interfaces if they are defines after being laid out
from a forward decl.

Ted Kremenek 0bb0909233 - Changed PathDiagnosticPiece::getLocation() to return a PathDiagnosticLocation
instead of a FullSourceLoc. This resulted in a bunch of small edits in various
  clients.
- Updated BugReporter to include an alternate PathDiagnostic generation
  algorithm for PathDiagnosticClients desiring more control-flow pieces.

 - PR3602.

 - As is inherent in the blanket forwarding options, this will only
   work if clang-cc happens to accept what the user passed. Users by
   and large should use driver options to interact with the
   preprocessor, if at all possible.

Steve Naroff 66afeb5968 Some "prep" work for handling ObjC @-string constants that contain UTF-8. No functionality change.
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).

Chris Lattner 8b14b98bab Fix a problem in ASTContext::addRecordToClass handling forward declarations.
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.
