Compile rustdoc on-demand

Fixes , fixes , and fixes .

Doesn't directly help with https://github.com/rust-lang/rust/issues/42686, since we need to rebuild just as much. In fact, this hurts it, since `./x.py doc --stage 0` will now fail. I'm not sure if it did before, but with these changes it runs into the problem where we attempt to use artifacts from bootstrap rustc with a non-bootstrap rustdoc, running into version conflicts. I believe this is solvable, but leaving for a future PR.

This means that rustdoc will no longer be compiled when compiling rustc, by default. However, it is still built from `./x.py build` (for hosts, but not targets, since we don't produce compiler toolchains for them) and will be built for doc tests and crate tests.

After this, the recommended workflow if you want a rustdoc is: `./x.py build --stage 1 src/tools/rustdoc` which will give you a working rustdoc in `build/triple/stage1/bin/rustdoc`. Note that you can add `src/libstd` onto the command to compile libstd as well so that the rustdoc can easily compile crates in the wild. `./x.py doc --stage 1 src/libstd` will document `libstd` with a freshly built rustdoc (if necessary), and will not rebuild rustc on modifications to rustdoc.

Copyright/license headers

(As discussed with @aturon and @est31. CC @rust-lang/core.)

Currently, rust-lang/rust includes notices that say things like
```
The Rust Project is copyright 2010, The Rust Project
Developers.
```
or
```
Copyright (c) 2010 The Rust Project Developers
```
or
```
// Copyright 2017 The Rust Project Developers. See the COPYRIGHT
// file at the top-level directory of this distribution and at
// http://rust-lang.org/COPYRIGHT.
```

These notices aren't accurate. "Copyright YYYY Some Name" has a specific legal meaning, and "The Rust Project Developers" isn't a legal entity. In practice, the actual legal structure is that all Rust contributors retain their copyrights when contributing to Rust, and just license them under MIT/Apache-2.0. Our legal notices should reflect that.

This came up because of RFC 2044, which proposed fixing this for the RFC repository. That effort started out by copying the rust-lang/rust notices, propagating this issue.

Based on discussion with @aturon, the two of us propose the following:

- Delete the per-file notices entirely, for any files licensed under the standard terms. (Keep notices for anything that's *not* MIT/Apache-2.0.)
  - An alternative to that would be to just delete the first paragraph of the standard notice, and keep the second paragraph that points to the MIT and Apache 2.0 licenses.
- Delete the first paragraph of LICENSE-MIT (the inaccurate pseudo-copyright line), leaving only the text of the MIT license.
- Edit the COPYRIGHT file to more accurately describe the situation (changing the pseudo-copyright line immediately under "longer version", and editing the text that starts with "additional copyright may be ...", to just always state that copyrights are retained by the Rust contributors, and licensed under MIT/Apache-2.0 (with the exceptions to that explicitly noted in that file).

If @rust-lang/core is fine with this proposal, I'd be happy to provide a pull request with the proposed fixes.

Extended error message for mut borrow conflicts in loops

RFC issue: https://github.com/rust-lang/rfcs/issues/2080

The error message for multiple mutable borrows on the same value over loop iterations now makes it clear that the conflict comes from the borrow outlasting the loop. The wording of the error is based on the special case of the moved-value error for a value moved in a loop. Following the example of that error, the code remains the same for the special case.

This is mainly because I felt the current message is confusing in the loop case : https://github.com/rust-lang/rust/issues/43437. It's not clear that the two conflicting borrows are in different iterations of the loop, and instead it just looks like the compiler has an issue with a single line.

f1de27fe6b COPYRIGHT: Provide a better explanation of Rust copyrights
Avoid implying that any copyrights have been assigned to a separate
entity (such as "The Rust Project Developers") Rust contributors retain
their copyrights, and do not assign them to anyone by contributing.

Remove the inaccurate notice, and provide a clear explanation. Avoid
stating that all files contain copyright notices and/or license notices,
and especially avoid suggesting that the license terms only apply to
files marked as such.

In the process, this also drops a separate notice that implies only some
copyrights are retained by contributors (suggesting that others are
not).

Fix printing regions with -Z verbose

When dumping MIR with `-Z verbose`, it would print regions on types, but not in the code. It seems the Rvalue printing code tried to be smart and guessed when the `Display` for `Region` would not possibly print anything.

This PR makes it no longer be smart, and just always use the `Display` like all the other code (e.g. printing types) does.

Make the "main" constructors of NonZero/Shared/Unique return Option

Per discussion in https://github.com/rust-lang/rust/issues/27730#issuecomment-303939441.

This is a breaking change to unstable APIs.

The old behavior is still available under the name `new_unchecked`. Note that only that one can be `const fn`, since `if` is currently not allowed in constant contexts.

In the case of `NonZero` this requires adding a new `is_zero` method to the `Zeroable` trait. I mildly dislike this, but it’s not much worse than having a `Zeroable` trait in the first place. `Zeroable` and `NonZero` are both unstable, this can be reworked later.
