ia64: Prevent GCC from clobbering r13.  Found by Luming You.

Without this change, GCC thinks it's OK to clobber r13.  It doesn't do it
very often, but it's enough if it does it once and it turns out
acpi_bus_receive_event() had code that would trigger this issue.
Fix by declaring r13 as a global register variable.
