Went through the jdk and found a few more places where `ArraysSupport::vectorizedHashCode` can be used, and a few where adhoc methods could be replaced with a plain call to `java.util.Arrays` equivalents. This patch addresses that.
After this, #12068, and #12077 I think we're reaching the limit of sensible direct use of `AS::vectorizedHashCode`. I've found a few places outside of java.base where `vectorizedHashCode` might be applicable, but none that seem important enough to warrant an export of this method outside of java.base. ------------- Commit messages: - Miscellaneous hashCode improvements in java.base Changes: https://git.openjdk.org/jdk/pull/12093/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=12093&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8300647 Stats: 44 lines in 3 files changed: 3 ins; 33 del; 8 mod Patch: https://git.openjdk.org/jdk/pull/12093.diff Fetch: git fetch https://git.openjdk.org/jdk pull/12093/head:pull/12093 PR: https://git.openjdk.org/jdk/pull/12093
