RFR: 8057174: MemoryMXBean tests -- TEST FAILED: chunkSize: 6291456 is less than YOUNG_GEN_SIZE: 8388608

[Stefan Karlsson]

Hi all,

Here's an updated version of the test:
http://cr.openjdk.java.net/~stefank/8057174/webrev.01.delta/
http://cr.openjdk.java.net/~stefank/8057174/webrev.01/

1) The max == -1 check would unnecessarily fail the test (if it ever 
would happen).

2) Some flags/configurations could increase the young gen size because 
of alignment restrictions in the heap sizing policies. I've updated the 
test to make sure that we run
a) with small G1 heap region sizes
b) without large pages

I had to remove the RunUtil.runTestKeepGcOpts targets to minimize the 
risk that someone will add arbitrary GC command line options to the test.

thanks,
StefanK
