`sse3` is missing from your list, right?

Should we simply use the CPU features detected by the VM? For example:
https://github.com/openjdk/jdk/blob/f12710e938b36594623e9c82961d8aa0c0ef29c2/src/hotspot/cpu/x86/vm_version_x86.hpp#L322-L327
https://github.com/openjdk/jdk/blob/f12710e938b36594623e9c82961d8aa0c0ef29c2/src/hotspot/cpu/aarch64/vm_version_aarch64.hpp#L105-L110

This test does that too:
