[Driver][Darwin] Pass -munwind-table when !UseSjLjExceptions.

This commit fixes a bug where clang/llvm doesn't emit an unwind table
for a function when it is marked noexcept. Without this patch, the
following code terminates with an uncaught exception on ARM64:

int foo1() noexcept {
  try {
    throw 0;
  } catch (int i) {
    return 0;
  }
  return 1;
}

int main() {
  return foo1();
}
