> since HIVE-16812 {{VectorizedOrcAcidRowBatchReader}} filters delete events based on min/max
ROW__ID in the split which relies on {{hive.acid.index}} to be in the ORC footer.  
> There is no way to generate {{hive.acid.index}} from a plain query as in HIVE-20699 and
so we need to make sure that we generate a SARG into delete_delta/bucket_x based on stripe
stats even the index is missing
