It appears that a change to the `cl-loop` macro in Emacs 27 introduced a
bug where certain clauses would be evaluated more than once in a loop
with a "when" clause.

See the following minimal example which finds the index of an element in
a list:


(cl-loop
=C2=A0for x in '(a b c d e)
=C2=A0for index =3D 0 then (1+ index)
=C2=A0when (eq x 'e)
=C2=A0return index)


In Emacs 26.1 this returns `4` as expected, but in Emacs 27.0.50 it
returns `7`, due to the index being incremented twice per loop. The same
occurs after a `emacs -Q` restart.

For reference here is the macroexpanded form of the above expression,
with the difference between 26 and 27 outlined (everything else is
identical):


(cl-block nil
=C2=A0 (let* ((--cl-var-- '(a b c d e))
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0(x nil)
