Reviewed by Dan Hecht.
This is helpful for considering the effect of different tagging
policies on how much memory we tag, both for performance and
(to a lesser extent) security.
This also demacroifies the tag-setting code while I'm touching it
anyways, as the actual code-change there is only one line and thus
should be easy to distinguish from the rest.
