func_documentation_string: Adds information about the first frame to incomplete stack traces.
  Safari and IE require this to get complete data on the first frame.
  @param {Object.<string, *>} stackInfo Stack trace information from
  one of the compute* methods.
  @param {string} url The URL of the script that caused an error.
  @param {(number|string)} lineNo The line number of the script that
  caused an error.
  @param {string=} message The error generated by the browser, which
  hopefully contains the name of the object that caused the error.
  @return {boolean} Whether or not the stack information was
  augmented.
