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.
