[LV] Don't predicate divs with invariant divisor when folding tail (#98904)
When folding the tail, at least one of the lanes must execute
unconditionally. If the divisor is loop-invariant no predication is
needed, as predication would not prevent the divide-by-0 on the executed
lane.
Depends on https://github.com/llvm/llvm-project/pull/98892.
