Port qemu-kvm's MCE support

commit c68b2374c9048812f488e00ffb95db66c0bc07a7
Author: Huang Ying <ying.huang@intel.com>

    Add MCE simulation support to qemu/kvm

    KVM ioctls are used to initialize MCE simulation and inject MCE. The
    real MCE simulation is implemented in Linux kernel. The Kernel part
    has been merged.
