345ba505ec rustc: Remove dylib crate type from most rustc crates
Now that procedural macros no longer link transitively to libsyntax,
this shouldn't be needed any more! This commit is an experiment in
removing all dynamic libraries from rustc except for librustc_driver
itself. Let's see how far we can get with that!

6bb60ef6f2 name the trait in ambiguous-associated-items fully qualified suggestion
We have the trait at this point, so we can name it in the error
message, rather than using "Trait" as a (potentially confusing)
placeholder.

Thanks to Yuki "@JohnTitor" Okushi for pointing out where to look (in
the same file) for a closely related issue for ambiguous associated
types (as opposed to items; that was #59225, except that one won't be
quite as easy to resolve, because we actually don't have the trait
`DefId` at that point).

Rollup merge of #62243 - petrochenkov:macrodoc, r=eddyb
Improve documentation for built-in macros

This is the `libcore` part of https://github.com/rust-lang/rust/pull/62086.
Right now the only effect is improved documentation.

The changes in the last few commits are required to make the `libcore` change compile successfully.

Because Weak doesn't Deref, so there's no reason for them to be only

Rollup merge of #60081 - pawroman:cleanup_unicode_script, r=varkor
Refactor unicode.py script

Hi, I noticed that the `unicode.py` script used some deprecated escapes in regular expressions. E.g. `\d`, `\w`, `\.` will be illegal in the future without "raw strings". This is now fixed. I have also cleaned up the script quite a bit.

## Escape deprecation

OK (note the `r`):
`re.compile(r"\d")`

Deprecated (from Python 3.6 onwards, see [here][link1] and [here][link2]):
`re.compile("\d")`.

[link1]: https://docs.python.org/3.6/whatsnew/3.6.html#deprecated-python-behavior
[link2]: https://bugs.python.org/issue27364

This was evident running the script using Python 3.7 like so:

```
$ python3 -Wall unicode.py
unicode.py:227: DeprecationWarning: invalid escape sequence \w
  re1 = re.compile("^ *([0-9A-F]+) *; *(\w+)")
unicode.py:228: DeprecationWarning: invalid escape sequence \.
  re2 = re.compile("^ *([0-9A-F]+)\.\.([0-9A-F]+) *; *(\w+)")
unicode.py:453: DeprecationWarning: invalid escape sequence \d
  pattern = "for Version (\d+)\.(\d+)\.(\d+) of the Unicode"
```

The documentation states that
> A backslash-character pair that is not a valid escape sequence now generates a DeprecationWarning. Although this will eventually become a SyntaxError, that will not be for several Python releases.

## Testing

To test my changes, I had to add support for choosing the Unicode version to use. The script will default to latest release (which is 12.0.0 at the moment, repo has 11.0.0 checked in).

The script generates the exact same output for version 11.0.0 with Python 2.7 and 3.7 and no longer generates any deprecation warnings:

```
$ python3 -Wall unicode.py -v 11.0.0
Using Unicode version: 11.0.0
Regenerated tables.rs.
$ git diff tables.rs
$ python2 -Wall unicode.py -v 11.0.0
Using Unicode version: 11.0.0
Regenerated tables.rs.
$ git diff tables.rs
$ python2 --version
Python 2.7.16
$ python3 --version
Python 3.7.3
```

## Extra functionality

Furthermore, the script will check and download the latest Unicode version by default (without the `-v` argument). The `--help` is below:

```
$ ./unicode.py --help
usage: unicode.py [-h] [-v VERSION]

Regenerate Unicode tables (tables.rs).

optional arguments:
  -h, --help            show this help message and exit
  -v VERSION, --version VERSION
                        Unicode version to use (if not specified, defaults to
                        latest available final release).
```

## Cleanups

I have cleaned up the code quite a bit, with Python best practices and code style in mind. I'm happy to provide more details and rationale for all my changes if the reviewers so desire.

One externally visible change is that the Unicode data will now be downloaded into `src/libcore/unicode/downloaded` directory suffixed by Unicode version:

```
$ pwd
.../rust/src/libcore/unicode
$ exa -T downloaded/
downloaded

[let_chains, 3/6] And then there was only Loop

Here we remove `hir::ExprKind::While`.
Instead, we desugar: `'label: while $cond $body` into:

```rust
'label: loop {
    match DropTemps($cond) {
        true => $body,
        _ => break,
    }
}
```

Per https://github.com/rust-lang/rust/issues/53667#issuecomment-471583239.
This is a follow up to https://github.com/rust-lang/rust/pull/59288 which did the same for `if` expressions.
