[PATCH] Emit the DIType for ObjC 'id<protocol>' as 'id' rather than objc_object* (fixes rdar://problem/12601916)

[jahanian]

+  // The frontend treats 'id' as a typedef to an ObjCObjectType,
+  // whereas 'id<protocol>' is treated as an ObjCPointerType. For the
+  // debug info, we want to emit 'id' in both cases.
+  QualType PointeeType = Ty->getPointeeType();
+  if (const ObjCObjectType *Obj = dyn_cast<ObjCObjectType>(PointeeType))
+    if (Obj->isObjCId() && (Obj->getNumProtocols() > 0)) {
+      return getOrCreateType(CGM.getContext().getObjCIdType(), Unit);
+    }

Please use isObjCQualifiedIdType instead.
