8072909: TimSort fails with ArrayIndexOutOfBoundsException on arrays longer than 1073741824

Hi Seth,

No. But, General direction of openjdk is mostly care about "do not 
introduce regression" in next release. All performance improvements are 
introduced with a very conservative way with checking that we do not 
slow down any previous behavior/benchmarks. I'm almost sure that simple 
increasing stack size do not introduce performance regression, but 
changing mergeCollapse() may do.

Please provide performance comparision of different fixes if you have it.
