[IA64] Add "model name" to /proc/cpuinfo
Linux ia64 port tried to decode the processor family number to something human-readable, but Intel brandnames don't change synchronously with updates to the family number. Adopt a more i386-like approach and just print the family number in decimal. Add a new field "model name" that uses PAL_BRAND_INFO to find the official name for the cpu, or on older systems, falls back to using the well-known codenames (Merced, McKinley, Madison).
