[OpenJDK 2D-Dev] RFR(S): 8145077: AIX: fix harfbuzz support

[Volker Simonis]

Hi,

could somebody please review this AIX-only fix which adds the harfbuzz
atomic primitives for AIX:

http://cr.openjdk.java.net/~simonis/webrevs/2015/8145077/
https://bugs.openjdk.java.net/browse/JDK-8145077

I plan to also submit this patch upstream to the harfbuzz project to
minimize the diffs between the upstream and the OpenJDK version.

Notice that although this is a client patch I plan to push this
directly to jdk9-dev because it fixes a build failure and I don't want
to wait for the next round-trip trough jdk9-client.

Thank you and best regards,
Volker
