// A factory function for turning a JS::Value argv into an nsIArray
// but also supports an effecient way of extracting the original argv.
// The resulting object will take a copy of the array, and ensure each
// element is rooted.
// Optionally, aArgv may be nullptr, in which case the array is allocated and
// rooted, but all items remain nullptr.  This presumably means the caller
// will then QI us for nsIJSArgArray, and set our array elements.
