hvm: allow pass-through of new FPU/ALU CPUID features

there are some new CPUID features that are safe for guests to see, as
they don't require OS awareness (FPU/ALU related instructions only).
Among features for new AMD CPUs there is also the PCLMULQDQ bit, which
Intel CPU have already for quite a while.
