When adding the pretenuring stuff we restricted the possible types we could apply this to, only allowing pretenuring for TypeObjects associated with an initialization site or 'new' script. This works fine for most scripts, but doesn't allow us to pretenure typed objects, which would be nice to do. (I've been testing perf with a copy of octane-splay rewritten to use typed objects.) We could carve out another exception for typed objects, but it seems better to just remove this unnecessary complexity as I don't think it was ever really warranted (we already try really hard to give types to objects which distinguish them based on how they are used, for TI to be effective.)
