add ksceKernelGetThreadCpuRegisters
This function is used to get the state of the registers for a SUSPENDED thread. It returns the registers in a two part structure. It's uncertian what the difference is between the two parts. It seems like its a user/kernel separation, but it's uncertain. It could also be a current/exception difference, but it is unconvincing. In normal usage on a suspended thread it seems to be the user aspect that contains valid values. When you query a suspended thread that has no had the opportunity to start yet, the kernel side is filled.
