Rename argument 'stack_size' to 'regs_off' in save_regs() and
restore_regs() since in reality 'stack_size' represents a particular
stack offset and 'regs_off' is the one in the caller argument.
Leter, another stack offset will be added to these two functions
for saving and restoring struct argument values.
