Allow the platform code to return a bitmask of running cores rather than just
a number of cores, this allows for a sparse set of CPUs. Implement support
for sparse core masks on Octeon.
XXX jeff@ suggests that all_cpus should include cores that are offline or
running other applications/OSes, so the platform API should be further
extended to allow us to set all_cpus to include all cores that are
physically-present as opposed to only those that are running FreeBSD.
