I should have looked on existing code. Yes, it also checks  `FLAG_IS_DEFAULT(UseAVX)` and you did not change behavior. Good.

I don't have anymore questions. I am currently running specjvm2008 on Cascade Lake with default settings with and without your changes to make sure performance stays the same (I don't know why it would change based on your changes but to be safe). I will let you know results.
