2e89b9bcba
implemented WAITPKG instruction set (#150) 
still missing : UMWAIT/TPAUSE should set CF flag if it was using OS
deadline and woken up after deadline (i.e. not from monitored store)
also not clear in the spec: should UWAITX/TPAUSE always wait until
deadline due to 'while(tsc<deadline)' statement ?
+include small fixes for AMD's MONITORX/MWAITX
