> Vectorized expressions have been implemented for UPPER(), LOWER() and LENGTH() for strings
but they have not been tied through end-to-end to work in queries. VectorizationContext needs
to be updated to do this.
> Also, LIKE support in VectorizationContext needs to be extended to support a string function
as an input.
