> Implement full, end-to-end support for CASE in vectorized mode, including new VectorExpression
class(es), VectorizationContext translation to a VectorExpression, and unit tests for these,
as well as end-to-end ad hoc testing. An end-to-end .q test is recommended but optional.
> This is high priority because CASE is a fairly popular expression.
