[PATCH, rs6000] Fix AIX test case failures

[Carl Love <cel@us.ibm.com>]

Segher:

I was requested to backport the patch for the AIX test case failures to
GCC 8.  The trunk patch applied cleanly to GCC 8.  I updated the
changelog patch, built and retested the patch on:

    powerpc64le-unknown-linux-gnu (Power 8 LE)  
    powerpc64-unknown-linux-gnu (Power 8 BE)
    AIX 7200-00-01-1543 (Power 8 BE)

With no regressions.

Please let me know if it is OK to apply the patch to the GCC 8 branch. 
Thanks.

                             Carl Love
