  [LV] Retrieve reduction resume values directly for epilogue vec. (NFC)

Use the reduction resume values from the phis in the scalar header,
instead of collecting them in a map. This removes some complexity from
the general executePlan code paths and pushes it to only the epilogue
vectorization part.
