Relax portable number check in byte compiler (bug#42147)
With bignums, the set of representable integers is no longer
platform-dependent, and since we use nothing but IEEE754 64-bit
floats, all numbers are now portable. Take advantage of this fact
to simplify constant-folding in the byte compiler, allowing it to
be applied more widely.
* lisp/emacs-lisp/byte-opt.el (byte-opt--portable-max)
(byte-opt--portable-min, byte-opt--portable-numberp): Remove.
(byte-opt--arith-reduce, byte-optimize-minus, byte-optimize-1+)
(byte-optimize-1-): Simplify: any number will do, and if N is a
number, then so are -N, N+1 and N-1.
