That doesn't help.  The problem is that the for loops assume that you
know that the offsets are at a constant distance, plus the distance.
This is already not trivial for the registers (is RAX at the highest or
lowest offset); but it could even be worse than hardcoded offsets for
selectors and descriptor caches.
