cl-preloaded.el (built-in-class): New type
Add classes describing the built-in types.
* lisp/emacs-lisp/cl-preloaded.el (built-in-class): New type.
(cl--define-built-in-type): New aux macro.
(all built-in types): "Define" them with it.
(cl--builtin-type-p): New aux function.
(cl--struct-name-p): Use it.
(cl--direct-supertypes-of-type, cl--typeof-types, cl--all-builtin-types):
Move the definitions to after the built-in classes are defined,
and rewrite to make use of those classes.
* lisp/emacs-lisp/cl-extra.el (cl-describe-type):
Accept two (unused) optional args, for use with `describe-symbol-backends`.
(describe-symbol-backends): Simplify accordingly and
add ourselves at the end.
(cl--class-children): New function.
(cl--describe-class): Use it. Also don't show a silly empty list of slots
for the built-in types.
