This is now integrated, so commits for 8u352 can commence,
after the usual review and approval process.

Backing out JDK-8284620 fixed the issue, so this does seem to be causing a regression
on AArch64. Filed https://bugs.openjdk.java.net/browse/JDK-8287537

I will back this out if it is not otherwise fixed by the time we come to freeze 8u342
in about a month's time.
