Currently the RustIrDatabase trait has methods that return Arc<SomeRustIrType>, but this doesn't map that well to rustc, as it must create these awkward types. We could instead have finer-grained methods. For the case of ADTs, we might have e.g.:
num_variants(adt_id)
num_fields(adt_id, variant_index)
field_type(adt_id, variant_index, field_index)
