      Overrides:
      makeOptimizedFunctionCall in class SystemFunction
      Parameters:
      visitor - the expression visitor
      contextInfo - information about the context item
      arguments - the supplied arguments to the function call. Note: modifying the contents of this array should not be attempted, it is likely to have no effect.
      Returns:
      either a function call on this function, or an expression that delivers the same result, or null indicating that no optimization has taken place
