Auto merge of #22117 - fhahn:fail-on-errors, r=nikomatsakis

At the moment, when compilation is stopped at a stop point (like `-Z parse-only`), `rustc` does not return an nonzero exit code even if there are errors (expect fatal ones, that cause it to panic immediately). As an example, compiling `src/test/compile-fail/doc-before-semi.rs` with `-Z parse-only` raises an error, but exists with 0.

Note that I could not use `sess.abort_if_errors()` in the macro, because `sess` is passed by value and move at some point.
