[PATCH] Append CXXDefaultInitExpr's wrapped expression to the CFG when visiting a constructor initializer

[Jordan Rose]

  Yeah, I'm not yet happy with the second approach. Notice how there are still no edges for the in-class initializer of Foo, even though that's clearly an important part of the path that leads to the null dereference. I don't want to block the main part of your patch (improving -Wuninitialized), so let's go with the option for now, and then do it right after.
