[CodeGen][NewPM] Port `LiveIntervals` to new pass manager (#98118)

- 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`.

RenameIndependentSubregs: Add missing sub-range for new IMPLICIT_DEFs (#89050)

Existing sub-ranges are correctly updated because new IMPLICIT_DEF is
added, but there is missing sub-range for IMPLICIT_DEF itself.
Because of missing sub-range in live-intervals for IMPLICIT_DEF,
register allocator does not know that IMPLICIT_DEF rewrites its
virtual sub-registers and can end up assigning overlapping physical
registers to them.
This results in deleting instructions that were defined by sub-registers
overwritten by IMPLICIT_DEF as they are now dead.

This is a helper function to very slightly simplify many calls to
MachineInstruction::getOperandNo.
