This commit is an implementation of the new compiler flags required by [RFC 1361][rfc]. This specifically adds a new `cfg` option to the `--print` flag to the compiler. This new directive will print the defined `#[cfg]` directives by the compiler for the target in question. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1361-cargo-cfg-dependencies

The `--print` flag was extended in rust-lang#31278 to accept `cfg`, but the usage message was not updated.
