Once conceptually owns a T outside the lock once it is initialized. This ensures we get the right impl for Sync: impl<T: Sync> Sync for Once<T>

Plus maybe an example of how one could exploit Once<T> if the PhantomData was not there?

What's the find_features parameter about?

create_target_machine calls is_pie_binary which requires crate_types. However when we are discovering the target CPU features, crate_types is uninitialized. So we pass in find_features to let create_target_machine assume that we aren't looking at a pie binary.

Should this use insert_same()?

The type inserted doesn't implement Eq, so it cannot use insert_same.

For this one, implementing Eq should be easy. Let's do it.

This might also be a candidate for insert_same().

Same thing, the type inserted doesn't implement Eq, so it cannot use insert_same.

Could you document this method, especially what the return value is.

init_locking and init_nonlocking should be documented to. I needed a while to see what these are about but the difference can be explained rather quickly.

Remove -Zperf-stats.

The included measurements have varied over the years. At one point there
were quite a few more, but rust-lang#49558 deleted a lot that were no longer
used. Today there's just four, and it's a motley collection that doesn't
seem particularly valuable.
I think it has been well and truly subsumed by self-profiling, which
collects way more data.
