Issue: acidanthera/bugtracker#531
For some reason that some msr not impletement in such hypervisor (QEMU/KVM/VMWare), so some logic may not work fine in a VM.
This commit will add cpuid hypervisor support to indicate whether we are
under visualization, then we do some tricks to make it work.

According to these links:
    1. [CPUID usage for interaction between Hypervisors and Linux.](https://lwn.net/Articles/301888/)
    2. [[Qemu-devel] [PATCH v2 0/3] x86-kvm: Fix Mac guest timekeeping by exposi](https://lists.gnu.org/archive/html/qemu-devel/2017-01/msg04344.html)

There is a "VMWare Timing" Node located at 0x40000010 where we can get
TSC/FSB Frequency.It is more sensable than get those freq in MSR which
most hypervisor not implemented yet (KVM/VMWare).
