Andrew Lenharth 2d86ea21dd Implement Value* tracking for loads and stores in the selection DAG. This enables one to use alias analysis in the backends. ...

(TRUNK)Stores and (EXT|ZEXT|SEXT)Loads have an extra SDOperand which is a SrcValueSDNode which contains the Value*.  Note that if the operation is introduced by the backend, it will still have the operand, but the value* will be null.
