With abstract materialization, any ast::Expression may map to the new sem::Materialize node. Because of this, we can't assume that an ast::CallExpression maps to a sem::Call, as it might be wrapped by a sem::Materialize. Remove the mapping, and fix up all the code that was relying on this. Fixes are done by either: • Calling `UnwrapMaterialize()->As<sem::Call>()` on the semantic expression. This is done when the logic may assume it's possible for the expression to be a Materialize node. • Using the explicit sem::Info::Get<sem::Call>() template argument to cast the semantic type to sem::Call. This is done when the logic either knows it is impossible for the expression to be a Materialize. The backends have been stubbed, as we'll want to emit the constant value for these nodes. It's likely that we'll just use the FoldConstants transform to strip all Materialize nodes from the tree. For now, be defensive.
