[PATCH] D43063: [DAGCombiner] Call ExtendUsesToFormExtLoad in (zext (and (load)))->(and (zextload)) even when the and does not have multiple uses

Pass N0 instead of N. But then pass the VT separately so the isTruncateFree call has the right VT to use for its look up since we're no longer passing the extend.
