Don't compile (+ X 0) as (* X 1)
Previously (+ X 0) was reduced to (+ X) which became (* X 1) in
codegen, but this is wrong for X = -0.0 and also slightly slower.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-plus): Don't reduce an
addition to (+ X) by eliminating zeros; retain one 0 argument.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test case.
