Change `function` so that when evaluating #'(lambda ...)
we return an object of type `interpreted-function` rather than
a list starting with one of `lambda` or `closure`.
The new type reuses the existing PVEC_CLOSURE (nee PVEC_COMPILED)
tag and tries to align the corresponding elements:
- the arglist, the docstring, and the interactive-form go in the
same slots as for byte-code functions.
- the body of the function goes in the slot used for the bytecode string.
- the lexical context goes in the slot used for the constants of
bytecoded functions.
The first point above means that `help-function-arglist`,
`documentation`, and `interactive-form`s don't need to
distinguish interpreted and bytecode functions any more.
Main benefits of the change:
- We can now reliably distinguish a list from a function value.
- `cl-defmethod` can dispatch on `interactive-function` and `closure`.
Dispatch on `function` also works now for interpreted functions but still
won't work for functions represented as lists or as symbols, of course.
- Function values are now self-evaluating. That was alrready the case
when byte-compiled, but not when interpreted since
(eval '(closure ...)) signals a void-function error.
That also avoids false-positive warnings about "don't quote your lambdas"
when doing things like `(mapcar ',func ...)`.
* src/eval.c (Fmake_interpreted_closure): New function.

`Vinternal_make_interpreted_closure_function`.

Change calling convention and use `make-interpreted-closure`.
* src/data.c (Fcl_type_of): Distinguish `byte-code-function`s from
`interpreted-function`s.
(Fclosurep, finterpreted_function_p): New functions.
(Fbyte_code_function_p): Don't be confused by `interpreted-function`s.
(Finteractive_form, Fcommand_modes): Simplify.
(syms_of_data): Define new type symbols and `defsubr` the two
new functions.
* lisp/emacs-lisp/cl-print.el (cl-print-object) <interpreted-function>:
New method.
* lisp/emacs-lisp/oclosure.el (oclosure): Refine the parent
to be `closure`.
(oclosure--fix-type, oclosure-type): Simplify.
(oclosure--copy, oclosure--get, oclosure--set): Adjust to
new representation.

* src/lread.c (bytecode_from_rev_list):
* lisp/simple.el (function-documentation):
* lisp/help.el (help-function-arglist): Remove the old `closure` case
and adjust the byte-code case so it handles `interpreted-function`s.
* lisp/emacs-lisp/cl-preloaded.el (closure): New type.
(byte-code-function): Add it as a parent.
(interpreted-function): Adjust parent (the type itself was already
added earlier by accident).
* lisp/emacs-lisp/bytecomp.el (byte-compile--reify-function): Adjust to
new representation.
(byte-compile): Use `interpreted-function-p`.
* lisp/emacs-lisp/byte-opt.el (byte-compile-inline-expand): Adjust to
new representation.
(side-effect-free-fns): Add `interpreted-function-p` and `closurep`.
* src/profiler.c (trace_hash, ffunction_equal): Simplify.
* lisp/profiler.el (profiler-function-equal): Simplify.

Use `interpreted-function-p`; adjust to new representation; and take
advantage of the fact that function values are now self-evaluating.
* lisp/emacs-lisp/lisp-mode.el (closure):
Remove `lisp-indent-function` property.
* lisp/emacs-lisp/disass.el (disassemble-internal): Adjust to
new representation.

Don't hardcode function values.
* doc/lispref/functions.texi (Anonymous Functions): Don't suggest that
function values are lists. Reword "self-quoting" to reflect the
fact that #' doesn't return the exact same object. Update examples
with the new shape of the return value.

* doc/lispref/lists.texi (Rearrangement):
* doc/lispref/control.texi (Handling Errors): Update examples to reflect
new representation of function values.
A function or macro body consisting of a single string literal now only
uses it as a return value. Previously, it had the dual uses as return
value and doc string, which was never what the programmer wanted and
had some inconvenient consequences (bug#69387).
This change applies to `lambda`, `defun`, `defsubst` and `defmacro`
forms; most other defining forms already worked in the sensible way.
* lisp/emacs-lisp/bytecomp.el (byte-compile-lambda):
Don't use a lone string literal as doc string.
* test/lisp/emacs-lisp/bytecomp-resources/warn-wide-docstring-defun.el
(foo): Update docstring warning test.
* doc/lispref/functions.texi (Function Documentation): Update.
