Bug: https://bugs.openjdk.java.net/browse/JDK-8205441
webrev: cr.openjdk.java.net/~prr/8205441
One last (!) chance to upgrade harfbuzz for JDK 11.
This pulls in the fix made upstream for building with SunStudio 12.6
I still needed to make a couple of makefile tweaks - one macro that
usually is defined by configure
for harfbuzz that we can just set, and one new warning to be disabled.
I also removed a file specific disabled warning for a file that was in
ICU and was removed in JDK 10
Built on all platforms.
