Do some rudimentary register content tracking.

This still does just mainly EXPR_SELECT, since that
is what I'm familiar with. It's also extremely lazy
about invalidating register content info, since any
code that hasn't been moved to the new format won't
do things properly.

Very much a work-in-progress, designed to eventually
allow us to generate some kind of half-readable code
from the SSA form.
