Fix byte-compilation of (+ -0.0) (bug#42597)

* lisp/emacs-lisp/bytecomp.el (byte-compile-associative):
Translate numerical identity expressions, such as (+ x) and (* x),
into (* x 1) since the previous translation (+ x 0) gets it wrong
for x = -0.0.
* test/lisp/emacs-lisp/bytecomp-tests.el
(byte-opt-testsuite-arith-data): Add test cases.
