Sorry for not making the right call first. But I find it is not correct to call
it `is_in_resume`. The actual semantic should be `not_in_ramp`. Since the it
should be true in destroy function (or other function in other ABI) too. Given
we generally don't use `no` in builtin names, let's change its name to
`is_in_ramp` and change the value correspondingly.
