I guess the assert should be adjusted, from gcc_assert (old_size != args_size);
to gcc_assert (old_size != args_size || find_reg_note (i3, REG_NORETURN,
NULL));
because we add the REG_ARGS_SIZE notes now even to noreturn calls where there
is no difference from previous args size.
Can't test it right now though.
