The id(s) of the argument bound to a single named parameter of a known signature, or undefined when
nothing is bound to it. A convenience over matchArgumentsToSignature for the common
"give me one parameter's argument" query, e.g.
argumentForParameter(ggplotCall.args, ggplotSignature, 'data') returns ggplot's data argument node(s).
