Vmware has historically used an INL instruction for this, but recent hardware versions support using VMCALL/VMMCALL instead, so use this method if supported at platform detection time. Explicitly code separate macro versions since the alternatives self-patching has not been performed at platform detection time. Also put tighter constraints on the assembly input parameters.
