ruby: fix MOESI_hammer directory to work with > 3GB memory
The MOESI_hammer directory assumes a contiguous address space, but X86
has an IO gap from 3-4GB. This patch allows the directory to work with
more than 3GB of memory on X86.
Assumptions: the physical address space (range of possible physical
addresses) is 0-XGB when X <= 3GB, and 0-(X+1)GB when X > 3GB. If there
is no IO gap this patch should still work.
