From 7583ccdc1f1d78e2a4b906a8ad9b55b0a1efcc4c Mon Sep 17 00:00:00 2001
From: James Molloy <james.molloy@arm.com>
Date: Mon, 5 Mar 2012 09:59:43 +0000
Subject: Fix a bug in the mangler where in 'namespace std { extern "C" {X;}
 }', X would not be seen to be in ::std::.

Migrate two other places where the same logic is used to use the helper function that already exists.
