I was getting pretty tired of the long compile times in between test runs. I thought they seemed particularly long for debug mode. It turns out that I had actually set `opt-level = 3` for running tests. This was because there were a select few tests that ran quite long in debug mode. But iteration time is important, so I trimmed down those tests and disabled optimizations. Tests run much more quickly now after making a change to the source code. We also add `cargo test --profile testrelease` to CI. This is just like normal tests, but disables `debug_assertions`. Jiff has a lot of extra stuff going on when `debug_assertions` are enabled due to its internal ranged integer abstraction. So it's useful to run tests without all that extra stuff too (reflecting what is intended to be run in production). Finally, we split win-gnu out to its own CI job and run a stripped down set of tests. Regretable, but it's *twice* as slow as the next slowest runner. That's sucks enough that we'll just live with worse test coverage until this becomes an obvious problem. (I'm also not even sure anyone is using this target anyway. It's not clear why anyone would.)
