Integrate jobserver support to parallel codegen This commit integrates the `jobserver` crate into the compiler. The crate was previously integrated in to Cargo as part of rust-lang/cargo#4110. The purpose here is to two-fold: * Primarily the compiler can cooperate with Cargo on parallelism. When you run `cargo build -j4` then this'll make sure that the entire build process between Cargo/rustc won't use more than 4 cores, whereas today you'd get 4 rustc instances which may all try to spawn lots of threads. * Secondarily rustc/Cargo can now integrate with a foreign GNU `make` jobserver. This means that if you call cargo/rustc from `make` or another jobserver-compatible implementation it'll use foreign parallelism settings instead of creating new ones locally. As the number of parallel codegen instances in the compiler continues to grow over time with the advent of incremental compilation it's expected that this'll become more of a problem, so this is intended to nip concurrent concerns in the bud by having all the tools to cooperate! Note that while rustc has support for itself creating a jobserver it's far more likely that rustc will always use the jobserver configured by Cargo. Cargo today will now set a jobserver unconditionally for rustc to use.
