JDK-8293563 is due to a macOS bug (or maybe a feature) that is resulting in the java heap not always being present in the core file. Running with `-XX:+AlwaysPreTouch` seems to work around this problem. This issue is only on macosx-aarch64, not x64.
------------- Commit messages: - Pretouch heap memory so it appears in the core dump.
