Paolo Bonzini 0723cc8a55 target/i386: add VMX features to named CPU models
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:

                if l.startswith(key):
                    ctl, bit = value

                        out[ctl] = out[ctl] + ' | '
                    else:
                        out[ctl] = '    [%s] = ' % ctl
                    out[ctl] = out[ctl] + bit

    for x in sorted(out.keys()):
        print("\n         ".join(textwrap.wrap(out[x] + ",")))

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.
