This allows using "-cpu Haswell,+vmx", which we did not really want to
support in QEMU but was produced by Libvirt when using the "host-model"
CPU model. Without this patch, no VMX feature is _actually_ supported
(only the basic instruction set extensions are) and KVM fails to load
in the guest.
This was produced from the output of scripts/kvm/vmxcap using the following
very ugly Python script:

Note that the script has a bug in that some keys apply to both VM entry
and VM exit controls ("load IA32_PERF_GLOBAL_CTRL", "load IA32_EFER",
"load IA32_PAT". Those have to be fixed by hand.
