message: Remove FIXME in `tests/compile-fail/panic/bad_unwind.rs`
diff: //! Unwinding when the caller ABI is "C" (without "-unwind") is UB.
  //! Currently we detect the ABI mismatch; we could probably allow such calls in principle one day
  //! but then we have to detect the unexpected unwinding.
  -//! FIXME: `-Zmiri-disable-abi-check` does not work for this test because function pointers are
  -//! always allowed to unwind.
  extern "C-unwind" fn unwind() {
  panic!();
