[POWERPC] ptrace accessors for special regs MSR and TRAP
[POWERPC] ptrace accessors for special regs MSR and TRAP

This isolates the ptrace code for the special-case registers msr and trap
from the ptrace-layout dispatch code.  This should inline away completely.
It cleanly separates the low-level machine magic that has to be done for
deep reasons, from the superficial details of the ptrace interface.
