Call this abstract value with the given arguments. The posargs and namedargs arguments may be modified by this function. Args: node: The CFGNode calling this function func: The cfg.Binding containing this function. args: Arguments for the call. alias_map: A datatypes.UnionFind, which stores all the type renaming information, mapping of type parameter name to its representative. Returns: A tuple (cfg.Node, cfg.Variable). The CFGNode corresponds to the function's "return" statement(s). Raises: function.FailedFunctionCall Make the call as required by this specific kind of atomic value, and make sure to annotate the results correctly with the origins (val and also other values appearing in the arguments).
