  Recommit "[VPlan] Mark Select VPInstructions as not having sideeffects."

With #70253 landed, selects for reduction results are explicitly used by
ComputeReductionResult and Selects can be marked as not having
side-effects again.

This reverts the revert commit 173032902c960d4d0d67b521d8c149553d8e8ba3.
