Crate bootstrap 

Implementation of bootstrap, the Rust build system.

This module, and its descendants, are the implementation of the Rust build system. Most of this build system is backed by Cargo but the outer layer here serves as the ability to orchestrate calling Cargo, sequencing Cargo builds, building artifacts like LLVM, etc. The goals of bootstrap are:

• To be an easily understandable, easily extensible, and maintainable build system.
• Leverage standard tools in the Rust ecosystem to build the compiler, aka crates.io and Cargo.
• A standard interface to build across all platforms, including MSVC
