Add macros for the GS (guest state) bit to the list of MSR bit definitions. On PowerPC cores that support embedded hypervisor mode, GS is cleared if the system is running in hypervisor state (and MSR[PR] is cleared), and set if it's running in guest state. See the Power ISA 2.06 specification for more information.
