Travis Geiselbrecht dcdc4f4b43 pulled over some stuff from newos:
at boot, per cpu, detect the cpu, pull down all the relevant cpuid bits and
save them into the per-cpu structure. Changed most of the code scattered here
and there that reads the cpuid to use a new api, x86_check_feature, which looks
at the saved bits.
Also changed the system_info stuff to read from these bits.
While i was at it, refreshed all the bits to be current.
