Repro without the qtest machinery:
$ lldb -- ./aarch64-softmmu/qemu-system-aarch64 -M n810 -s -S -monitor
stdio -machine accel=qtest
then run and type 'info jit' at the monitor prompt.

I don't think it makes a great deal of sense to be able to call into
the TCG dump_exec_info() statistics routine if we never initialized
the TCG accelerator (because we're using -accel=qtest). Not sure
it makes much sense if -accel=kvm, for that matter...
thanks
