I've gone over this with [~hsubramaniyan] and I think this looks good.  Will see how the unit
test results look.

> Add support to allow queries referencing VARCHAR columns and expression results to run
efficiently in vectorized mode. This should re-use the code for the STRING type to the extent
possible and beneficial. Include unit tests and end-to-end tests. Consider re-using or extending
existing end-to-end tests for vectorized string operations.
