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