Likely makes more sense to never create the ReErased in the first place...

That would require changing the type_of query behavior for anon consts -- not sure what that would break though. I guess anon consts should be treating all those lifetimes as ReStatic like other consts though 🤔

@jackh726: Oh... sooo this calls the typeck query on the body of the AnonConst, so all non-late lifetimes (incl ReStatic) are erased during writeback. Don't think I can avoid getting ReErased when I call tcx.type_of.
