- Add `LiveIntervalsAnalysis`. - Add `LiveIntervalsPrinterPass`. - Use `LiveIntervalsWrapperPass` in legacy pass manager. - Use `std::unique_ptr` instead of raw pointer for `LICalc`, so destructor and default move constructor can handle it correctly. This would be the last analysis required by `PHIElimination`.
