JDK-8134540 - Much nearly duplicated code for PerfMemory support
Description
In perfMemory_aix.cpp we still have O_NOFOLLOW related fallback coding for  AIX version < 7.X. 
This is no longer needed, because we do not support any more AIX versions < 7.X  in coming jdk13,  so cleanup is possible.

Maybe the container support should be put in it's own file, the Linux and BSD support is probably the same.

> Can you also do JDK-8134540? I started it a long time ago but I can't really test on aix. There were only minor differences. I looked into JDK-8134540 . AIX might have only minor diffs, but Linux has quite a few (I think because of container support). So it is maybe better to leave the files where they are.

hi Coleen, I'll post a patch for this bug soon. However on some AIX machines one has to consider http://www-01.ibm.com/support/docview.wss?uid=isg1IV63861 too, O_NOFOLLOW was broken there .

[~mbaesken] are you still working on this? Can you also do JDK-8134540? I started it a long time ago but I can't really test on aix. There were only minor differences.
