Move the things that actually test dependency behavior into the regular test suite, now that we can do that. :)

keep only byteorder as a "demo" dependency, it is a leaf and builds quickly.

[cargo-miri] support nextest

Add the ability to run `cargo miri nextest list` and `cargo miri nextest run`.

[cargo-nextest](https://nexte.st) is a new test runner for Rust maintained mostly by myself. It has several new features, but the most relevant to miri is the fact that it runs [each test in its own process](https://nexte.st/book/how-it-works.html#the-nextest-model). This gives miri users better leak detection (https://github.com/rust-lang/miri/issues/1481) for free, for example.

See https://github.com/nextest-rs/nextest/issues/181 for discussion, including comments by `@eddyb` and `@RalfJung.`

Future work might be to have miri read [the list of tests](https://docs.rs/nextest-metadata/latest/nextest_metadata/struct.TestListSummary.html) (or [test binaries](https://docs.rs/nextest-metadata/latest/nextest_metadata/struct.BinaryListSummary.html)) generated by `nextest list`. `@eddyb` thinks that might be useful.

I tested `cargo miri nextest run` against smallvec, and it worked great.

Note: Running tests out of archives is currently broken, as the comment in run-test.py explains.

Add a scheme for always using the default toolchain, running clippy and fmt before running any other command

I keep forgetting to run rustup-toolchain on rebases across toolchain updates

I also keep forgetting to run rustfmt and clippy. The former isn't run by vscode if I don't explicitly save (I have autosave on).

check for extern static size mismatches

Also handle get_alloc_extra the same throughout Stacked Borrows. I don't think this `unwrap` can actually cause an ICE since another part of SB will raise an error before, but still, seems strange to do this inconsistently in retagging vs expose_ptr.

Allow ui tests to have dependencies in a reliable way

This completely sidesteps the issue that compiletest-rs has where old artifacts of a dependency cause `multiple available crates of name XXX` errors. At this point I think we've reached feature parity for clippy, too, so I'm going to try publishing a version once this is merged.

0844e46049 Auto merge of #2391 - RalfJung:stderr, r=oli-obk 
on an error, always print the unnormalized stderr

Currently we skip this if a stderr diff was printed, but the stderr diff is normalized, so e.g. one cannot learn line numbers from it.

Is there a way to get the diff to only print the parts the differ, like a usual `diff -u`? Currently it always seems to print the full output, so with a long stderr we now get doubly long test results even if the diff is actually rather small.

And also expand the cache integrity checks to cover this case.
