RFR (XS): 8060116: After JDK-8047976 gc/g1/TestSummarizeRSetStatsThreads fails

[Marcus Larsson]

Hi,

I would like reviews for the following patch modifying the 
TestSummarizeRSetStatsThreads. The patch modifies the test so that it 
does not set ParallelGCThreads=0, since this is no longer allowed [1]. 
Additionally the test is modified to not use the 0 value for 
G1ConcRefinementThreads as this is part of a different test [2], and 
should not really be tested here.

Tested locally with jtreg.

Thanks,
Marcus
