As suggested by @nikomatsakis here.

The current version of chalk used by the experimental -Zchalk flag is v0.9.0, which is over a year old. Since v0.9.0, chalk has seen a lot of further development, and the intent is to eventually upgrade rustc to use a more recent chalk.

However, it will take a decent chunk of effort to upgrade the current experimental chalk support, and it is currently blocking at least some PRs due to chalk:0.9.0's use of unstable features. So for the interim until the next chalk release and experimental rustc integration, we remove the chalk-specific code from rustc.

FWIW, I've gotten (locally) the Chalk-related code updated to the latest Chalk master (with some modifications that'll get PRed soon). It compiles but -Z chalk tests are broken.

Just for good measure, I suppose I should cc @rust-lang/wg-traits

OK so I talked to @jackh726 and we agreed that we could go ahead and land this, we'll just "git revert" it and build our replacement. I did a review and it looks good, but it needs a rebase.

@CAD97 if you want to rebase, you can go ahead and make it r=nikomatsakis afterwards.
