This patch adds the split-lock emulation.
If a #AC is caused by instruction with LOCK prefix then
emulate it, otherwise, inject it back as it used to be.
1. Kick other vcpus of the guest to stop execution
and set the TF flag to have #DB if the guest has more
than one vcpu.
2. Skip over the LOCK prefix and resume the current
vcpu back to guest for execution.
3. Notify other vcpus to restart exception at the end
of handling the #DB since we have completed
the LOCK prefix instruction emulation.
