Description
It's worth redesigning the Step execution model to allow Steps to run in parallel, which would speed up pretty much any bootstrap invocation. This would be a big win as almost every bootstrap invocation involves running many Steps. Making bootstrap faster would benefit everyone especially those doing frequent build iterations while working on rust-lang/rust.

Research direction
Start by tracing the bootstrap Step execution model and how a bootstrap invocation sequences its steps. Determine which steps can run concurrently and what dependencies or ordering constraints must be preserved. Done means bootstrap invocations safely execute independent steps in parallel and demonstrate a measurable speedup.
