I suppose UseKNLSetting is a x86 specific option, is this okay for other platforms?

These 2 test cases should be removed from test/hotspot/jtreg/ProblemList.txt[1] in your patch. See #221 for more details.

Yes, you don't need to add new run commands in tests. We are running these tests with these flags on avx512 machines in our testing.

[vnkozlov]

Looks good. I will run tests.
