bug#44540: 27.1.50; Regression when evaluating signalling forms in *scratch*

[Philipp Stephani]

Select the *scratch* buffer and enter

(car 123)

Then hit C-j.  In Emacs 26, this will correctly pop up the debugger.  In
the Emacs 27 release branch, however, you'll get an error

Symbol’s function definition is void: cl-print-to-string-with-limit

Seems like some `require' is missing somewhere?
