Ensure that segment.base == segment.selector << 4 when entering the real
mode on Intel so that the CPU will not bark at us.  This fixes some old
protected mode demo from http://www.x86.org/articles/pmbasics/tspec_a1_doc.htm.

Instead of having each architecture do it individually, we
do this in the arch-independent code (just x86 as of now).

This is a little more accurate (since it counts actual reloads, not potential
reloads), and reverses the sense of the statistic to measure a bad event like
most of the other stats (e.g. we want to minimize all counters).
