Declare qregister[u]int, an integer the size of the machine's word
In almost all platforms, sizeof(qregisterint) == sizeof(void*) ==
sizeof(qptrdiff). It's different for architectures that have a pointer
with a size different from the machine word. This allows us to declare
variables of the most optimal size, even if the pointers are too wide or
too narrow.
The only currently-known architectures to match that case are the ILP32
builds on x86-64 (a.k.a "x32") and IA-64 (option -milp32, only available
on HP-UXi), which have 64-bit registers but 32-bit pointers.
