This uses derivative to derive Clone/PartialOrd/Ord/Hash for types in rustc_type_ir. This doesn't derive PartialEq/Eq yet, because I have no idea why those are generating slower implementations from derivative.

Overall result: no relevant changes - no action needed

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

I split this out from the PartialEq and Eq impls, which seems to be the problem with perf in #117184 (comment) (see: #117408)

ironically "feature_allow_slow_enum" wasn't even the cause for the slowness: #117409 (comment)
