Upgrade NodePtr to RefPtr

Allows Nodes to be moved from one Block to another without copying them.
When targeting GLSL 1.30 LegacyConverter has a sequence where it flattens
an interface block and later checks the type of those variables through
their declaration pointer.  This caused memory errors because the
original nodes were destroyed in the flatten operation.
