Why does cfun->can_throw_non_call_exceptions and
cfun->can_delete_dead_exceptions exist btw? Now that both
flag_non_call_exceptions and flag_delete_dead_exceptions are Optimization,
set_cfun adjusts that on switching the function, so I think it be the same.
Ok, {fn,fun,src_cfun}->can_throw_non_call_exceptions might be faster when it
looks at other functions than opt_for_fn.
