KVM: Add VT-x machine check support
VT-x needs an explicit MC vector intercept to handle machine checks in the hyper visor. It also has a special option to catch machine checks that happen during VT entry. Do these interceptions and forward them to the Linux machine check handler. Make it always look like user space is interrupted because the machine check handler treats kernel/user space differently. Thanks to Jiang Yunhong for help and testing.
