This PR proposes to add a new method `MemorySegment::maxByteAlignment` that returns the maximum byte alignment of a segment (both heap and native segments).
Clients can then use this method to determine if a segment is properly aligned for any given layout (e.g. following a `MemorySegment::reinterpret` operation). ------------- Commit messages: - Fix imports and copyright - Update maxByteAlignment docs - Improve doc and tests - Add a MS::maxByteAlignment method Changes: https://git.openjdk.org/jdk/pull/18779/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=18779&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8329997 Stats: 134 lines in 4 files changed: 128 ins; 2 del; 4 mod Patch: https://git.openjdk.org/jdk/pull/18779.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/18779/head:pull/18779 PR: https://git.openjdk.org/jdk/pull/18779
