Changes look fine. I approve them.

The only confusion I have is platform name in title (yes, I know it is because Graal still uses AMD64 as platform name). May be better use x86 in title (I assume it is not 64-bit specific feature). I see these features are implemented in Intel's CPUs. Do AMD also have them?
