types: get rid of PreserveInfo 

We don't need the indirection. We store the preserve mask directly in
the entry, and create a new one if it doesn't exists (which is exactly
what the current code does in a roundabout way).

Incidentally this fixes a bug where the effective modifier mask of the
entries' preserve[] wasn't calculated, so the virtual modifiers had no
effect there.
