Hi Zhongxing,

This is an excellent idea, but I don't think putting this logic in  
GRSimpleVals is the right place.  This is really a property of the  
particular implementation of Store, since that handles the abstraction  
of "memory".  Specifically, this logic seems tied to BasicStore and  
BasicStoreManager respectively.

I think the most logical place would be to put it in  
BasicStoreManager's implementation of "getInitialStore()".  We can  
either pass LiveVariables& to getInitialStore(), or pass  
GRStateManager& to getInitialStore() (and migrate the LiveVariables&  
instance variable from GRExprEngine to GRStateManager).
