	eh_return function.  Correct expected value of altivec_save_offset
	when using save_world.  Describe save of R0 to stack when using
	save_world.  Describe stack pointer adjustment when using
	save_world.  Remove duplicated eh_return parameter register saving.
	Update sp_offset variable after save_world.
