Subject: [PATCH] Extend AArch64 support

This adds to IcedTea 6 a patch that extends the support for AArch64 in
its version of HotSpot, allowing the portable Zero virtual machine to
be built for that platform.

The patch added is a backport of the one prepared for JDK 9 by the
OpenJDK AArch64 Porting Project, available (as of 11 June 2020) for
download from https://openjdk.java.net/jeps/237.
