[SCEV] Make sure LCSSA is preserved when re-using phi if needed.
If we insert a new add instruction, it may introduce a new use outside
the loop that contains the phi node we re-use. Use fixupLCSSAFormFor to
fix LCSSA form, if needed.
This fixes a crash reported in
https://github.com/llvm/llvm-project/pull/147824#issuecomment-3124670997.
