* 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.
