[IA64-SGI] - New SN hardware support - addr_macros

Browse Source 
Update the SN address macros so that they work on both shub1 
and shub2. Most of the code to support shub2 was added last year
but this patch fixes a few bugs and adds macros to help generate
both processor-specific physical addresses & numalink physical
addresses. More cleanup & optimization will be done later.
