Currently the default release profile enables LTO and single CGU builds, which is very slow to build. Most tests are better run with optimizations enabled since it allows testing a much larger number of inputs, so it is inconvenient that building can sometimes take significantly longer than the tests. Remedy this by doing the following: * Move the existing `release` profile to `release-opt`. * With the above, the default `release` profile is untouched (16 CGUs and thin local LTO). * `release-checked` inherits `release`, so no LTO or single CGU. This means that the simple `cargo test --release` becomes much faster for local development. We are able to enable the other profiles as needed in CI. Tests should ideally still be run with `--profile release-checked` to ensure there are no debug assetions or unexpected wrapping math hit. `no-panic` still needs a single CGU, so must be run with `--profile release-opt`. Since it is not possible to detect CGU or profilel configuration from within build scripts, the `ENSURE_NO_PANIC` environment variable must now always be set.
