* Don't emit byte op-code annotations in LIMPLE to optimize for compile-time

Saves 10~15% in bootstrap time.

	* lisp/emacs-lisp/comp.el (comp-op-case): Don't emit op-code
	annotaitons.
	(comp-limplify-lap-inst, comp-add-cond-cstrs-simple)
	(comp-add-cond-cstrs, comp-tco-func): Update accordingly.
