I don't think there is one yet.  Depending on what you mean by "entirely
a comment", it could be:

    (save-excursion
      (forward-line 0)
      (< (line-end-position)
         (let ((ppss (syntax-ppss)))
           (when (nth 4 ppss)
             (goto-char (nth 8 ppss)))
           (forward-comment (point-max))
           (point))))
