The FIXME in `dotimes'

[Philip Kaludercic]

I've always been wondering about this comment in the `dotimes' macro:

  ;; FIXME: This cost disappears in byte-compiled lexical-binding files.
  (let ((temp '--dotimes-limit--)
    ...

It appears to have been written 11 years ago, when lexical binding was
not that wide-spread.  Has the time come to follow the recommendation?
