  Log Message:
  -----------
  [VPlan] Keep start value in VPWidenIntOrFpInductionRecipe (NFC).

This patch updates VPWidenIntOrFpInductionRecipe to hold the start value
for the induction variable. This makes the start value explicit and
allows for adjusting the start value for a VPlan.

The flexibility will be used in further patches.
