/**
* IPA type for data flow nodes.
*
* Flow between SSA variables are computed in `Essa.qll`
* Nodes broadly fall into three categories.
*
* Flow from SSA variables to control flow nodes are generally via uses.
*
* Flow from control flow nodes to SSA variables are generally via assignments.
*
* The current implementation of these cross flows can be seen in `EssaTaintTracking`.
* - Control flow nodes: Flow between these is based on use-use flow computed via an SSA analysis.
* - Module variable nodes: These represent global variables and act as canonical targets for reads and writes of these.
* - Synthetic nodes: These handle flow in various special cases.
