Part I of ad@'s performance improvements for aarch64
- Remove memory barriers from the atomic ops. I don't understand why those
are there. Is it some architectural thing, or for a CPU bug, or just
over-caution maybe? They're not needed for correctness.
- Have unlikely conditional branches go forwards to help the static branch
predictor.
