Greg Woolsey 6390202491 Bug #61841 - Unnecessary long computation when evaluating VLOOKUP on all column reference
Found some optimizations in the general evaluation framework related to blank cells in rows beyond the last defined row of a sheet.

I don't see any issue with passing a bit of context down deeper into this framework, as it's all POI-internal and only had one calling path.

See the above bug for the performance analysis.  Not specifically related to VLOOKUP, but improves that case by more than 2/3 as well.
