Turns out I misinterpreted what having the lang item defined meant, as I forgot they're loaded cross-crate. re-r? @alexcrichton on the latest commit which detects if the panic impl is local or not, which should be correct. |

…, r=alexcrichton Move has_panic_handler to query Moves us off of a global Once instead re-querying the lang item each time. The conditions on when we set it to true change a little (previously we'd make sure a few more lang items were `Some`) but I think they in practice don't matter, we won't compile later on if we don't have them.
