Wow! I've always wanted to contribute to Rustc itself and this is a nice opportunity. I will try to implement this feature with some mentoring.

@petrochenkov You are familiar with most of this, right? Could you perhaps write up some instructions?

Partial implementation completed as of 2019-06-12. Implementation was done in #60669 by @c410-f3r and the PR was reviewed by @petrochenkov and @Centril.

#61238 still needs to be done for a full implementation.
