[PATCH] D25777: [Sema][TreeTransform] Re-create DesignatedInitExpr when it has a field designator with a valid FieldDecl

[Manman Ren via cfe-commits]

manmanren added a comment.

It makes sense to rebuild the expression when a field designator stores a 
FieldDecl.

Thanks for working on this!

                                                D.getFieldLoc()));
+      if (D.getField())
+        ExprChanged = true;
----------------
Please add comment here on why we need to set ExprChanged to true.
