  -----------
  [LV][NFC] Simplify initialization of MinProfitableTripCount (#113445)

Iteration runtime check confirms whether the trip count is greater than
VFxUF at least. Therefore, there is no need to adjust the
MinProfitableTripCount to VF if it is zero.
Retaining the original MinProfitableTripCount information is also
beneficial for supporting more profitable runtime checks in the future.
