bug#35186: 26.1; confusing error message and location on eager dotted pair evaluation

[Ernesto Alfonso <erjoalgo@gmail.com>]

Originally reported on the flycheck bug tracker:

https://github.com/flycheck/flycheck/issues/1557#event-2240962448

Using a dotted pair that accidently is eagerly evaluated results in a
confusing error message and location.
    
From the flycheck tracker, fmdkdd's steps to reproduce:

    $ cat foo.el
    (defun foo ()
      (some irrelevant form)
      (a . b))
    $ emacs -Q --batch -f batch-byte-compile foo.el
    In toplevel form:
    /tmp/foo.el:1:8:Error: Wrong type argument: sequencep, b
