Some stuff used by rustc that doesn't have many dependencies

Originally extracted from rustc::back, which was nominally the compiler 'backend', though LLVM is rustc's backend, so rustc_target is really just odds-and-ends relating to code gen and linking. This crate mostly exists to make rustc smaller, so we might put more 'stuff' here in the future. It does not have a dependency on LLVM.

rustc_target contains some very low-level details that are specific to different compilation targets and so forth.

For more information about how rustc works, see the rustc dev guide.
