Paolo Bonzini 44d65ea161 ringtest: use link-time optimization 
By using -flto and -fwhole-program, all functions from the ring implementation
can be treated as static and possibly inlined.  Force this to happen through
the GCC flatten attribute.

Partial implementation of various ring layouts, useful to tune virtio design.
Uses shared memory heavily.

Typical use:

# sh run-on-all.sh perf stat -r 10 --log-fd 1 -- ./ring
