      3 ; This used to cause a crash.  A standard load is converted to a pre-increment
      4 ; load.  Later the pre-increment load is combined with a subsequent SRL to
      5 ; produce a smaller load.  This transform invalidly created a standard load
      6 ; and propagated the produced value into uses of both produced values of the
      7 ; pre-increment load.  The result was a crash when attempting to process an
      8 ; add with a token-chain operand.
