Modified Files:
	syssrc/sys/arch/sh5/include: frame.h
	syssrc/sys/arch/sh5/sh5: cpu_switch.S db_interface.c exception.S
	    genassym.cf process_machdep.c trap.c vm_machdep.c

Log Message:
Move registers r10-r13 over to the Caller-saved set, at least as far
as intrframe and trapframe are concerned.

According to the ABI, only the low 32-bits of these registers are
guaranteed to be preserved by the callee. Therefore, we need to
preserve all 64-bits of them in the interrupt trampoline.
