Currently the kvm-check-branches.sh script calculates the number of CPUs
and passes this to the kvm.sh --cpus command-line argument. This works,
but this commit saves a line by instead using the new kvm.sh --allcpus
command-line argument.

This commit adds a kvm-check-branches.sh script that takes a list
of commits and commit ranges and runs a short rcutorture test on all
scenarios on each specified commit. A summary is printed at the end, and
the script returns success if all rcutorture runs completed without error.
