Rust's RFC 2837 demoted the
i686-apple-darwin
target to Tier 3, so that target will not be downloadable anymore through rustup starting from Rust 1.42.0. The change will also land on nightly soon, and that will prevent docs.rs from updating the rustwide toolchain.This PR removes
i686-apple-darwin
from the list of targets we build, and adds code to remove it automatically from existing rustwide workspaces.This is ready for review, but we should hold off deploying it until we announce the demotion on the blog.
