Create a similar rollup

In particular:
  - `unwrap_unchecked()` for `Option`.
  - `unwrap_unchecked()` and `unwrap_err_unchecked()` for `Result`.

These complement other `*_unchecked()` methods in `core` etc.

Currently there are a couple of places it may be used inside rustc
(`LinkedList`, `BTree`). It is also easy to find other repositories
with similar functionality.

Fixes rust-lang#48278.

Apparently `tidy` has a hard limit of 2830 tests in the
`src/test/ui/issues/` directory, and this test hit that limit.

`src/test/ui/consts/` is probably a better location anyway.
I have trouble parsing the the wording "type parameter parameter".

Use elapsed wall time spent on codegen_to_LLVM_IR for all CGUs as a
whole, rather than the sum for each CGU (the distinction matters for
parallel builds, where some CGUs are processed in parallel).

The cargo check was checking that every dependency had an `extern crate`.
The compiler has not used `extern crate` in a long time (edition 2018).
The test was broken (the call to `!super::filter_dirs(path)` was backwards).
This just removes it since it is no longer valid.
These exceptions are no longer necessary.
This will cause a failure due to the warning after the next beta branch
as rust-lang#79812 will hit beta.
Converting LHS of an assignment does not work, so avoid suggesting that.

Fixes rust-lang#81293
Don't suggest it if the last statement doesn't have a semicolon

BTreeMap: test all borrowing interfaces and test more chaotic order behavior

Inspired by rust-lang#81169, test what happens if you mess up order of the type with which you search (as opposed to the key type).

tidy: Some code cleanup.

This is just some cleanup that shouldn't have any change in behavior.  (See commit messages for more details.)

* Remove cargo check. This test wasn't working, and is no longer valid.
* Remove edition filter exceptions. They are no longer necessary.
* Remove unnecessary trailing semicolon.  Otherwise the warning will prevent tidy from building after the beta branch.

Fix assertion in `MaybeUninit::array_assume_init()` for zero-length arrays

That assertion has a false positive ([playground](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2018&gist=63922b8c897b04112adcdf346deb1d0e)):
```rust
#![feature(maybe_uninit_array_assume_init)]

use std::mem::MaybeUninit;

enum Uninhabited {}

fn main() {
    unsafe {
        // thread 'main' panicked at 'attempted to instantiate uninhabited type `Uninhabited`'
        MaybeUninit::<Uninhabited>::array_assume_init([]);
    }
}
```
*Previously reported in rust-lang#80600 (comment)

This PR makes it ignore zero-length arrays.
