* byte-opt.el (byte-compile-butlast): Move up in file.
(byte-optimize-plus): Don't call
byte-optimize-delay-constants-math (bug#1334). Use
byte-optimize-predicate to optimize constants.
(byte-optimize-minus): Don't call
byte-optimize-delay-constants-math. Remove zero arguments first
if possible. Call byte-optimize-predicate to optimize constants.
(byte-optimize-multiply): Remove optimizations for arguments of 0
and 2, which may be inaccurate. Optimize (* x -1) to (- x). Call
byte-optimize-predicate.
(byte-optimize-divide): Leave runtime errors unchanged.
Optimize (/ x 1) to (+ x 0). Remove optimizations for arguments of
0 and 2.0, which may be inaccurate. Call byte-optimize-predicate.
