Add missing side-effect-free and error-free properties

Any function that is pure is also side-effect-free and some are also
error-free.  Right now these have to be declared separately.

* lisp/emacs-lisp/byte-opt.el (side-effect-free-fns): Add
bool-vector-count-consecutive, bool-vector-count-population,
bool-vector-subsetp, copysign, isnan, lax-plist-get, ldexp, memql,
regexp-opt and string-to-syntax.
(side-effect-and-error-free-fns): Add type-of.
* lisp/subr.el (kbd, string-replace): Declare side-effect-free.
