  -----------
  [VPlan] Handle conditional ordered reductions with scalar VFs.

VPReductionRecipe::execute was not handling predicates for ordered
reduction with scalar VFs, which was causing a crash. Thsi patch adds
dedicated handling for scalar VFs when dealing with the condition.
The other operands are already handled in a similar fashion below.

Fixes #70988.
