This PR fixes the purity flag of `relax.vm.call_tir_dyn` and another few "kill" ops. Their purity flags were set to True, which made them possible to be removed by `remove_all_unused`. * `relax.vm.call_tir_dyn` works by mutating the input args in place, which is not pure. * though the "kill" ops have no actions so far, their semantics suggest that they are impure. A regression test is added to prevent the unexpected removal from happening again.
