We have two new SIE exit codes dealing with instructions. 104 (0x68) for a secure instruction interception, on which the SIE needs hypervisor action to complete the instruction. We can piggy-back on the existing instruction handlers.
108 which is merely a notification and provides data for tracking and management. For example this is used to tell the host about a new value for the prefix register. As there will be several special case handlers in later patches, we handle this in a separate function.
