Subject: bug#61733: emacs-dump-portable fails in 29.0.60

Redumping libraries that create overlays on loading fails now, but did
not in 28.2.  For example, the following line from icomplete makes it
fail while dumping:
emacs -Q -batch --eval '(defvar icomplete-overlay (make-overlay
(point-min) (point-min) nil t t)  "Overlay used to display the list of
completions.")' --eval '(dump-emacs-portable "test.pdmp")'
will dump core.

Redumping libraries that treesit-font-lock-rules will also fail now due
to a "weird pseudovector".  This is not a regression itself, as it is a
new feature, but it has been added to libraries that previously redumped
without issue, such as sh-script.  So
emacs -Q -batch --eval '(load "progmodes/sh-script")' --eval
'(dump-emacs-portable "test.pdmp")'
will fail.

These issues make switching to 29.1 a non-starter for users relying on
redumping to make startup time reasonable.
