01c890ee96 [incremental] Specialize encoding and decoding of Fingerprints
This saves the storage space used by about 32 bits per `Fingerprint`.
On average, this reduces the size of the `/target/{mode}/incremental`
folder by roughly 5%.

Fixes #45875

Shorten names of some compiler generated artifacts.

This PR makes the compiler mangle codegen unit names by default. The name of every codegen unit name will now be a random string of 16 characters. It also makes the file extensions of some intermediate compiler products shorter. Hopefully, these changes will reduce the pressure on tools with path length restrictions like buildbot. The change should also solve problems with case-insensitive file system.

a713c67a68 Skip linker-output-non-utf8 test on Apple
This test fails on APFS filesystems with the following error:

mkdir: /Users/ryan/Code/rust/build/x86_64-apple-darwin/test/run-make/linker-output-non-utf8.stage2-x86_64-apple-darwin/zzz�: Illegal byte sequence

This is due to APFS now requiring that all paths are valid UTF-8. As
APFS will be the default filesystem for all new Darwin-based systems the
most straightforward fix is to skip this test on Darwin as well as
Windows.

2e33c89ff1 Auto merge of #47231 - ereslibre:clean-emitted-diagnostics, r=nrc
Clean emitted diagnostics when `reset_err_count` is called.

When external tools like `rustfmt` calls to `reset_err_count` for handler
reusing, it will set the error count on the handler to 0, but since
https://github.com/rust-lang/rust/pull/47146 the handler will contain
status that will prevent the error count to be bumped if this handler is
reused.

This caused `rustfmt` idempotency tests to fail:

fix the doc-comment-decoration-trimming edge-case rustdoc ICE

This `horizontal_trim` function strips the leading whitespace from
doc-comments that have a left-asterisk-margin:

```
  /**
   * You know what I mean—
   *
   * comments like this!
   */
```

The index of the column of asterisks is `i`, and if trimming is deemed
possible, we slice each line from `i+1` to the end of the line. But if, in
particular, `i` was 0 _and_ there was an empty line (as in the example
given in the reporting issue), we ended up panicking trying to slice an
empty string from 0+1 (== 1).

Let's tighten our check to say that we can't trim when `i` is even the same
as the length of the line, not just when it's greater. (Any such cases
would panic trying to slice `line` from `line.len()+1`.)

Resolves #47197.

Add help message for incorrect pattern syntax

When I was getting started with rust I often made the mistake of using `||` instead of `|` to match multiple patterns and spent a long time staring at my code wondering what was wrong.

for example:

```
fn main() {
    let x = 1;

    match x {
        1 || 2 => println!("1 or 2"),
        _ => println!("Something else"),
    }
}

```

If you compile this with current rustc you will see

```
error: expected one of `...`, `..=`, `..`, `=>`, `if`, or `|`, found `||`
 --> test.rs:5:11
  |
5 |         1 || 2 => println!("1 or 2"),
  |          -^^ unexpected token
  |          |
  |          expected one of `...`, `..=`, `..`, `=>`, `if`, or `|` here

error: aborting due to previous error
```

With my proposed change it will show:
```
error: unexpected token `||` after pattern
 --> test.rs:5:11
  |
5 |         1 || 2 => println!("1 or 2"),
  |           ^^
  |
  = help: did you mean to use `|` to specify multiple patterns instead?

error: aborting due to previous error

Make normalize_and_test_predicates into a query

From #44891.

I'm not real solid on how `dep_graph` stuff works, but if a node is going to have a key (again, not sure how important that is), then the key needs to be `Copy`. So since `normalize_and_test_predicates` only had one out-of-module use, I changed that call site to use a new function, `substitute_normalize_and_test_predicates` which is the query and enables having the arguments be `Copy`. Hopefully this makes sense.
