Fix SPEEDTEST instructions and output
* `--nocapture` hasn't been needed anymore since forever (even before `ui_test`)
* the result was dividing by 1000 instead of the number of test runs, giving bogus (but still useful for the purpose) timing results.
changelog: fix SPEEDTEST instructions and output
Add `SPEEDTEST`
In the `master` branch, we currently don't have any way to test the performance of a single lint in changes.
This PR adds `SPEEDTEST`, the environment variable which lets you do a speed test on a lint / category of tests with various configuration options.
Maybe we should merge this with `lintcheck` 🤔
See the book page for more information.

Port clippy away from compiletest to ui_test
Reasons to do this:
* runs completely on stable Rust
* is easier to extend with new features
* has its own dogfood test suite, so changes can be tested in [the `ui_test` repo](https://github.com/oli-obk/ui_test)
* supports dependencies from crates.io without having to manually fiddle with command line flags
* supports `ui-cargo`, `ui`, `ui-toml` out of the box, no need to find and run the tests ourselves
One thing that is a big difference to `compiletest` is that if a test emits *any* error, you need to mark all of them with `//~ ERROR:` annotations. Since many clippy tests did not have annotations, I changed many lints to be `warn` in their test so that only the `stderr` output is tested.
TODO:
* [ ] check that this still works as a subtree in the rustc repo
