The primary motivation is to get the changes from https://github.com/tokio-rs/tracing/pull/990. Example output: ``` $ RUSTDOC_LOG=debug rustdoc +rustc2 warning: some trace filter directives would enable traces that are disabled statically | `debug` would enable the DEBUG level for all targets = note: the static max level is `info` = help: to enable DEBUG logging, remove the `max_level_info` feature ``` - Remove useless test This was testing for an ICE when passing `RUST_LOG=rustc_middle`. I noticed it because it started giving the tracing warning (because tests are not run with debug-logging enabled). Since this bug seems unlikely to re-occur, I just removed it altogether. |

The driver crate is effectively the "main" function for the rust
compiler. It orchestrates the compilation process and "knits together"
the code from the other crates within rustc. This crate itself does
not contain any of the "main logic" of the compiler (though it does
have some code related to pretty printing or other minor compiler
options).
For more information about how the driver works, see the rustc dev guide.
