Thanks!  I think a such function will be very useful.  Perhaps it
could just contain the code run when selecting the *Rescan* item?
Something like this:

(defun imenu-refresh ()
  "Refresh the imenu."
  (imenu--cleanup)
  (setq imenu--index-alist nil)
  (imenu-update-menubar)
  t)

(defun imenu--menubar-select (item)
  "Use Imenu to select the function or variable named in this menu ITEM."
  (if (equal item imenu--rescan-item)
      (imenu-refresh)
    (imenu item)
    nil))
