This is purely a performance patch: InstrRefBasedLDV used to use three DenseMaps to store variable values, two for long term storage and one as a working set. This patch eliminates the working set, and updates the long term storage in place, thus avoiding two DenseMap comparisons and two DenseMap assignments, which can be expensive.
