RFR: 8188131: [PPC] Increase inlining thresholds to the same as other platforms

[Kazunori Ogata]

Hi all,

Please review a change for JDK-8188131.

Bug report: https://bugs.openjdk.java.net/browse/JDK-8188131
Webrev: http://cr.openjdk.java.net/~horii/8188131/webrev.00/

This change increases the default values of FreqInlineSize and 
InlineSmallCode in ppc64 to 325 and 2500, respectively.  These values are 
the same as aarch64.  The performance of TPC-DS Q96 was improved by about 
6% with this change.


Regards,
Ogata
