Class CapturedVariablesArgumentNode

A synthetic argument representing the values of the variables captured by the callable being called. This argument represents a single object where all the values are stored as attributes. This is also known as the environment part of a closure.

This is used for tracking flow through captured variables.

TODO: We might want a synthetic node here, but currently that incurs problems with non-monotonic recursion, because of the use of resolveCall in the char pred. This may be solvable by using CallGraphConstruction::Make in stead of CallGraphConstruction::Simple::Make appropriately.
