RFR(M): 8211425: Allocation of old generation of java heap on alternate memory devices - G1 GC

[Kharbas, Kishor]

Thank you are the comments.

I have new webrev at - http://cr.openjdk.java.net/~kkharbas/8211425/webrev.10/
http://cr.openjdk.java.net/~kkharbas/8211425/webrev.09_to_10/

Worked on the comments including limiting newsize and removed parallel gc parts.

Jtregs test results:
(1) OpenJDK tip :                    passed: 1,798; failed: 36; error: 181 
(2) Parallel patch, no flag :   passed: 1,796; failed: 36; error: 183
(3) Parallel patch with flag : passed: 1,568; failed: 51; error: 230

Most new failures are not related and passed when re-run, like ones in,
compiler/intrinsics/bmi/
compiler/rtm/locking

One failure may be related which I am trying to debug, which is,
gc/vector/ObjectArrayLow/TestDescription.java

Thanks,
Kishor
