Mask out SRR1 bits that aren't exported to the MSR. This appears to fix a strange condition with X on 32-bit PowerBooks I observed, caused by one of these bits getting set in the mcontext, but not set in the thread, which may be a symptom of another problem, more difficult to diagnose. Since these bits aren't exported anyway, this change makes it more explicit that the bits aren't MSR-related in SRR1. MFC after: 3 weeks
