Update docs for ToUppercase/ToLowercase structs

Rollup merge of #23428 - Manishearth:ast-doc, r=steveklabnik
I often have to run `ast-json` or look into the pretty-printer source to figure out what the fields of an AST enum mean. I've tried to document most of what I know (and some semi-obvious stuff).
Rollup merge of #23475 - nikomatsakis:closure-ret-syntax, r=acrichto
Require braces when a closure has an explicit return type. This is a [breaking-change]: instead of a closure like `|| -> i32 22`, prefer `|| -> i32 { 22 }`.
Rollup merge of #23462 - alexcrichton:stabilize-cloned, r=aturon
This commit stabilizes the `cloned` iterator after tweaking the signature to
require that the iterator is over `&T` instead of `U: Deref<T>`. This method has
had time to bake for awhile now and it's not clear whether the `Deref` bound is
worth it. Additionally, there aren't clear conventions on when to bound and/or
implement the `Deref` trait, so for now the conservative route is to require
references instead of `U: Deref<T>`.
To change this signature to using `Deref` would technically be a
backwards-incompatible change, but it is doubtful that any code will actually
break in practice.

This commit clarifies some of the unstable features in the `str` module by
moving them out of the blanket `core` and `collections` features.
The following methods were moved to the `str_char` feature which generally
encompasses decoding specific characters from a `str` and dealing with the
result. It is unclear if any of these methods need to be stabilized for 1.0 and
the most conservative route for now is to continue providing them but to leave
them as unstable under a more specific name.

It also implements some necessary traits (`IntoBytes`, `Seek`, `Read`, `BufRead`) for fixed-size arrays (also related to #21725) and adds test for #17233, which seems to be resolved.

Safe fns are no longer subtypes of unsafe fns, but you can coerce from one to the other.
This is a [breaking-change] in that impl fns must now be declared `unsafe` if the trait is declared `unsafe`. In some rare cases, the subtyping change may also direct affect you, but no such cases were encountered in practice.

Auto merge of #23376 - eddyb:die-tydesc-die, r=nikomatsakis
Final remnant of reflection is gone. Also, virtual `Trait` destructors are no longer tied to `Box`.
That means they can be used to drop any instance of the type (used in libarena to replace TyDesc).
This is [breaking-change] for direct users of intrinsics:
* use `intrinsics::type_name::<T>()` instead of `(*intrinsics::get_tydesc::<T>()).name`
* the only way to get the destructor is from a trait object's vtable (see libarena changes)

This upcast coercion currently never requires vtable changes. It should be generalized.
This is a [breaking-change] -- if you have an impl on an object type like `impl SomeTrait`, then this will no longer be applicable to object types like `SomeTrait+Send`. In the standard library, this primarily affected `Any`, and this PR adds impls for `Any+Send` as to keep the API the same in practice. An alternate workaround is to use UFCS form or standalone fns. For more details, see <https://github.com/rust-lang/rust/issues/18737#issuecomment-78450798>.

Remove subtyping for object types and replace with an *upcast* coercion.
This upcast coercion currently preserves the vtable for the object, but
eventually it can be used to create a derived vtable. The upcast
coercion is not introduced into method dispatch; see comment on #18737
for information about why. Fixes #18737.

This removes the error case of the compression functions, the only errors that
can occur are incorrect parameters or an out-of-memory condition, both of which

Also introduces an extensible `Error` type instead of returning an `Option`.
The type implements a destructor so you can't destructure it.
