I'd prefer single optimization features (using a bit set) but it's just
my opinion.

AFAIK no, but it really depends on what you call optimizations.

Seems OK. I think you'd better to use a private hypercall (num > 0x100)

VTi already has a few flags. I don't remember if you can reuse the field but
adding a new one is ok (for me).
