mem: Use a flag instead of address bit 63 for generic IPRs
Using address bit 63 to identify generic IPRs caused problems on SPARC, where IPRs are heavily used. This changeset redefines how generic IPRs are identified. Instead of using bit 63, we now use a separate flag (GENERIC_IPR) a memory request.
