	* sim_calls.c (sim_create_inferior): Assert that
	psim_write_register succeeded.
	(sim_fetch_register, sim_store_register): Make "regname" constant.
	Delete Altivec hack.  Return result from psim_read_register /
	psim_write_register.
	* psim.h (psim_read_register, psim_write_register): Change return
	type to int.  Update comments.
	* psim.c: Update copyright.
	(psim_stack): Assert that the psim_read_register worked.
	(psim_read_register, psim_read_register): Return the register's
	size.  Allocate the cooked buffer dynamically.
	* hw_register.c: Update copyright.
	(do_register_init): Check that psim_write_register succeeded.
	* hw_init.c: Update copyright.
	(create_ppc_elf_stack_frame, create_ppc_aix_stack_frame): Assert
	that the register transfer worked.
