addfdb52 - [LV] Skip select cost for invariant divisors in legacy cost model.

[LV] Skip select cost for invariant divisors in legacy cost model. For UDiv/SDiv with invariant divisors, the created selects will be hoisted out. Don't compute their cost for each iteration, to match the more accurate VPlan-based cost modeling. Fixes https://github.com/llvm/llvm-project/issues/159402.
