- Autodetect the correct PARLEVEL is none is specified
- Allow overriding PARLEVEL in the environment
- Parallelize initial LLVM build
- Allow building a chain of rustc versions using TestRustcBootstrap.sh
The makefile changes improve build time by allowing LLVM build to run on multiple threads, while also avoiding some issues related to certain dependencies being attempted multiple times simultaneously (e.g. two threads both trying to download the same rust tarball).
Once the mrustc, official and chained builds become identical, it makes no more sense to do official and chained builds for any remaining versions, as all inputs to the builds are then identical.
