docs: This function adds a comma-separated list as is specified by an ARRAYLIT
  node with the associated skipIndexes array.  This is a space optimization
  since we avoid creating a whole Node object for each empty array literal
  slot.
  @param firstInList The first in the node list (chained through the next
  property).
