Add ./x.py check src/{libstd,libtest,rustc}.
This currently only supports a limited subset of the full compilation, but is likely 90% of what people will want and is possible without building a full compiler (i.e., running LLVM). In theory, this means that contributors who don't want to build LLVM now have an easy way to compile locally, though running tests won't work.
