  Log Message:
  -----------
  [VPlan] Use VPSCEVExpander in convertToStridedAccesses (#208939)

Expand SCEVs to VPInstructions, falling back to expanding to IR
instructions. Expanding to VPInstructions has the advantage that the
expansion would be made visible to the VPlan optimization pipeline,
allowing existing simplifications to kick in.
