kernel: x86 SSE improvements

Browse Source 
* Prepend x86_ to non-static x86 code
* Add x86_init_fpu function to kernel header
* Don't init fpu multiple times on smp systems
* Verified fpu is still started on smp and non-smp
* SSE code still generates general protection faults
  on smp systems though
