> Add support to allow queries referencing DATE columns and expression results to run efficiently
in vectorized mode. This should re-use the code for the the integer/timestamp types 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 integer and/or timestamp operations.
