This function returns a static pointer used with SgNode::p_freepointer.

This function returns returns an internally held (function local data) static pointer value used by SgNode::p_freepointer to identify non-NULL value representing valid IR node in memory pool. A NULL pointer represents last entry in the memory pool. This value allows us to distinguish the entries, and not require additional memory storage on each IR node.
