[jdk8u-dev] RFR: 8067941: [TESTBUG] Fix tests for OS with 64K page size.

[Dongbo He]

Hi,

I would like to backport this patch to fix tests for OS with 64K page size.
Patch does not apply cleanly: 
JDK-8062854[1] move StackOverflowBug.java and Test8009761.java to corresponding subfolders.
Test8009761.java context is different because JDK-8021775[2] and JDK-8011397[3] doesn't in jdk8u.
Change to TestGCLogMessages.java is excluded because it was added in JDK-8027962[4].
Chnage to WBStackSize.java is excluded because JDK-8032970[5] does not exist in 8.

I changed Xss in StackOverflowBug.java, Test8009761.java, TestRecursiveReplacedException.java, 
StackOverflowGuardPagesOff.java, TestStackBangMonitorOwned.java and TestStackBangRbp.java from
392k to 512k according to JDK-8159335[6], because JDK-8173339[7] changed StackShadowPages to 20, xss needs at least 456k.

Testing: checked that StackOverflowBug.java, Test8009761.java, TestRecursiveReplacedException.java,
StackOverflowGuardPagesOff.java, TestStackBangMonitorOwned.java, TestStackBangRbp.java,
TestHumongousAllocInitialMark.java, TestCMSHeapSizeFlags.java, TestG1HeapSizeFlags.java,
TestParallelHeapSizeFlags.java, TestSerialHeapSizeFlags.java fails without the patch
and passes with the patch on Aarch64 with 64K page size.
