[8u] RFR Backport of 8217896: Make better use of LCPUs when building on AIX

[Andrew Leonard]

Hi,
Please can I request a review of this updated patch for 8217896 to 
backport to jdk8u. The patch is essentially the same, but jdk8 the 
build-performance.m4 is in a different location, with a different 
copyright year, and the generated-configure.sh generation.. I have built 
and tested this on our AIX machines.
http://cr.openjdk.java.net/~aleonard/8217896/webrev.03/
Once reviewed I will add the jdk8u-fix-request.
Thanks
Andrew
