JSImportCall
JavaScript dynamic import of the form import(arg).
JavaScript dynamic import of the form import(arg).
This form is its own node, rather than using something like
JSFunctionApply(JSImport())
because import is not a first-class term in JavaScript.
ImportCall is a dedicated syntactic form that cannot be
dissociated.
