Optimise `append` calls
Add the transforms
(append) -> nil
(append X) -> X
(append '(X) Y) -> (cons 'X Y)
(append (list X) Y) -> (cons X Y)
(append (list X...) nil) -> (list X...)
and the argument transforms:
(list X...) (list Y...) -> (list X... Y...)
nil -> ;nothing
CONST1 CONST2 -> CONST1++CONST2
(list CONSTANTS...) -> '(CONSTANTS...)
(the last three for non-tail arguments only)
* lisp/emacs-lisp/byte-opt.el: New.
