Early normalisation of setq during macroexpand-all allows later stages, cconv, byte-opt and codegen, to be simplified and duplicated checks to be eliminated. * lisp/emacs-lisp/macroexp.el (macroexp--expand-all): Normalise all setq forms to a sequence of (setq VAR EXPR). Emit warnings if necessary. * lisp/emacs-lisp/cconv.el (cconv-convert, cconv-analyze-form): * lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker): * lisp/emacs-lisp/bytecomp.el (byte-compile-setq): Simplify. * test/lisp/emacs-lisp/bytecomp-tests.el: Adapt and add tests. * test/lisp/emacs-lisp/bytecomp-resources/warn-variable-setq-nonvariable.el; * test/lisp/emacs-lisp/bytecomp-resources/warn-variable-setq-odd.el: New files.
