Object.getOwnPropertyDescriptor(function(){"use strict"},"caller").get.hasOwnProperty("prototype") should be false

Object.getOwnPropertyDescriptor(function(){"use strict"},"caller").get.hasOwnProperty("prototype") should be false. But, nashorn evaluates this to true

But this is also true for built-in functions such as "parseInt".

    parseInt.hasOwnProperty("prototype")

should be false as well. Nashorn evaluates that to true.
