Proposal: JDK-8217896: Make better use of LCPUs when building on AIX

[Andrew Leonard]

Hi,
Please can I get a sponsor for this build performance enhancement on AIX, 
by better determining the number of LCPUs on smt AIX machines:
    https://cr.openjdk.java.net/~aleonard/8217896/webrev.00/
My testing shows up to 30% improved build times when leveraging the 
available LCPUs.
Many thanks
Andrew
