GCC is reporting a NULL pointer dereference when compiling aio_wait_kick() with LTO.
The issue is that test-nested-aio-poll.c does not call qemu_init_main_loop(). It doesn't _need_ to because it never calls AIO_WAIT_WHILE(), but it seems that LTO does not do enough dead-code elimination to catch that. Fortunately aio_wait_kick() is only used in few places, and only in block layer or system emulation code; and this test only needs the core event loop functionality. It does not even need iothreads. So remove everything that calls aio_wait_kick(), which is nice for coverage compared to adding the call to qemu_init_main_loop(). Reported-by: Richard W.M.
