Please search for public APIs you want to remove/change before doing so.

There was no need for this "cleanup", it's just a change for the sake of change, and now some level of control has been removed from custom drivers. Maybe all rustc_interface changes like this should go through MCPs?

It looks like there's no way to capture the compiler output without abusing std::io::set_output_capture, and even that likely doesn't apply to the compiler because it seems like std::io::{stdout,stderr} bypass output capture (and only print!/eprint!/panic! gets captured).

Might be easier to try to create a Session {...} by hand, even though that feels somewhat daunting, hopefully most of it is unnecessary (since this is just a test driver).

(Not expecting this to get reverted, hence the workarounds, but it would be nice to not have repeats in the future)

Should have done that. My bad. @nnethercote do you want to revert this PR and add a comment about it's use?

We've already worked around it, don't worry about a revert:

Turns out that I got turned around and Session {...} is impossible because that function is in rustc_session itself, but we were still able to find a way to create an artificial Session and still mutate it afterwards.

Like I said before, the more important point is that more care should be taken in the future.

EDIT: btw I opened an issue for us moving off of these weird unit tests:

Make termcolor types public in rustc_errors
da86cdf 
After rust-lang#114104, `rust-gpu` is unable to create a custom `Emitter` as the bounds have changed to include `WriteColor`.

I was able to work around this by adding `termcolor` as a direct dependency, but I believe this should be exposed as part of `rustc_errors` proper.

See rust-lang#102992 for why `rust-gpu` needs to create a custom emitter.
