Description

Implement full, end-to-end support for IF 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 IF is the most popular conditional expression.
