From 99ddbfbcc3d0e8a52c8f8a4ec22462d9e00c1c6a Mon Sep 17 00:00:00 2001
From: Tom Sepez <tsepez@chromium.org>
Date: Wed, 3 Feb 2016 16:38:30 -0800
Subject: Make CXFA_Data sub-classes ctors explicit.

Remove implicit CXFA_Node* operator.
Add bool() operator.
Remove IsExistInXML() which duplicates bool operator.
