[IA64] Update processor_info features 



Add the printing of additional processor features to proc_features.

Based on Rev 2.2 of Volume 2 of "Intel Itanium Architecture Software
Developer's Manual" (January 2006) fields (pages 2:430-2:432).
This patch gets the features back in sync with the spec.
