  [LV] Move IV bypass value creation out of ILV (NFC)

createInductionAdditionalBypassValues is only used for epilogue
vectorization now. Move it out of ILV, which means we do not have to
thread through ExpandedSCEVs and also don't have to track the bypass
values in ILV. Instead, directly create them if needed after executing
the epilogue plan. This moves more the epilogue specific logic out of
the generic executePlan.
