Description

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.
