Description
The typical reason to download nightly rustc in ./x is to build the standard library. That only needs rustc + std. However, bootstrap currently also downloads rustc-dev. To minimize download time, mobile data usage, and disk space consumption, it'd be nice to avoid the download when it is not needed.

Research direction
Start in bootstrap's download-rustc path, using ./x and the standard-library build flow described in the issue. Check when rustc-dev is requested versus when only rustc and std are needed. Done means standard-library builds avoid downloading rustc-dev while workflows that need it still receive it.
