Manish Goregaokar a2840f3560 Rollup merge of #22278 - nikomatsakis:rustc-error, r=nikomatsakis
Add `#[rustc_error]` annotation, which causes trans to signal an error
if found on the `main()` function. This lets you write tests that live
in `compile-fail` but are expected to compile successfully. This is
handy when you have many small variations on a theme that you want to
keep together, and you are just testing the type checker, not the
runtime semantics.
