This needed a rebase after 5e13b0f240397b2, see attached v18.

Looking at the changes in that commit, I also ended up re-ordering the
feature flags in pg_cpu.h, so we have the 128/256/512 bit registers
first, and then hypervisor and TSC flags after the 512 bit registers.

No other changes.

Thanks,
Lukas
