Module compile

Implementation of compiling various phases of the compiler and standard library.

This module contains some of the real meat in the bootstrap build system which is where Cargo is used to compile the standard library, libtest, and the compiler. This module is also responsible for assembling the sysroot as it goes along from the output of the previous stage.

RustcLink 🔒

RustcLink copies all of the rlibs from the rustc build into the previous stage’s sysroot. This is necessary for tools using rustc_private, where the previous compiler will build a tool against the next compiler. To build a tool against a compiler, the rlibs of that compiler that it links against must be in the sysroot of the compiler that’s doing the compiling.
