[DebugInfo][LoopStrengthReduce] Fix missing debug location updates (#97519)
Fix #97510 .

Note that, for the new phi instruction `NewPH`, which replaces the old
phi `PH` and the cast `ShadowUse`, I choose to propagate the debug
location of `PH` to it, because the cast is eliminated according to the
optimization semantics.
