The `vldap1` and `vstl1` RCPC3 intrinsics introduced in standard library unconditionally use `AtomicI64`. This breaks builds on target that do not support 64-bit atomics, such as `aarch64-unknown-none` with `max-atomic-width` set to 0. This commit adds a `#[cfg(target_has_atomic = "64")]` guard to these intrinsics
