Rustfix update

This updates to rustfix 0.6.0. One of the key changes here is https://github.com/rust-lang/rustfix/pull/195 which changes rustfix to apply multi-part suggestions. One of the tests needs to updated because there are some overlapping suggestions which rustfix cannot handle. The solution is to only apply the machine-applicable suggestions to avoid the overlapping issue.

This also includes a minor change to compiletest to provide better error messages with rustfix.
