This PR cleans up a bunch of test steps and adds metadata to them. I didn't yet touch the most complicated step (CompileTest), I'm leaving that for another PR.

Testing anything on stage 0 is only possible for compiletest and with build.allow-compiletest-stage0. Testing anything else on stage 0 will either produce a nice error or crash with a stage being subtracted below zero.

The tool wasn't useful for anything, it was only built as a part of the test, but we can just use `cargo test` and `cargo run` in the test, no need to (pre-)build the tool itself.

This PR was rebased onto a different master commit. Here's a range-diff highlighting what actually changed.

Rebasing is a normal part of keeping PRs up to date, so no action is needed—this note is just to help reviewers.
