bug#48261: 28.0.50; Optimize `eql' to `eq' for fixnums

[Mattias Engdegård]

Good!

+  (and (fixnump o) (<= -536870912 o 536870911)))

Maybe write (<= (- (ash 1 29)) o (1- (ash 1 29))) instead.

+                            (cl-every

Are you sure this is a good idea? See comment in the beginning of bytecomp.el.
Maybe just hold your nose and keep the existing (memq nil (mapcar ...)) hack; 
the list is usually short.

(We really should have fast, readable, always-available standard functions or 
macros for 'some' and 'every' on lists.)
