RFR backport: 8207766: [testbug] Adapt tests for Aix.

[Andrew Leonard]

Hi,
Please can I request a review to backport  8207766: [testbug] Adapt tests 
for Aix.?
https://bugs.openjdk.java.net/browse/JDK-8207766
The patch needs alterations, which I have done and tested here: 
http://cr.openjdk.java.net/~aleonard/8207766/webrev.00/
This enables the full set of com/sun/jdi to work on AIX.
Many thanks
Andrew
