// The LiveIntervalCalc class is an extension of LiveRangeCalc targeted to the
// computation and modification of the LiveInterval variants of LiveRanges.
// LiveIntervals are meant to track liveness of registers and stack slots and
// LiveIntervalCalc adds to LiveRangeCalc all the machinery required to
// construct the liveness of virtual registers tracked by a LiveInterval.
