CI: add a script for dynamically computing CI job matrix It would be great if was easier to run specific CI workflows locally, and also to allow us to spawn a specific CI workflow by bors, to enable running arbitrary try builds. See discussion [here](https://rust-lang.zulipchat.com/#narrow/stream/242791-t-infra/topic/CI.20workflows.20refactoring). This PR is a first step in that direction. - Moves the definition of CI runners and (for now) PR jobs into a separate `jobs.yml` file. - Adds a simple Python script that reads the file, decides which jobs should be active for the current CI workflow, and prints them as JSON to their output. - The PR job then reads this output and generates its job matrix based on it. By moving the job definitions from `ci.yml` into a separate file, we can handle it programmatically, which should make it easier to both do local execution of CI jobs and also to do arbitrary try builds.
This directory contains some source code for the Rust project, including:
- The bootstrapping build system
- Various submodules for tools, like cargo, tidy, etc.
