…alidating, r=oli-obk Normalize field types before checking validity I forgot to normalize field types when checking ADT-like aggregates in the MIR validator. This normalization is needed due to a crude check for opaque types in `mir_assign_valid_types` which prevents opaque type cycles -- if we pass in an unnormalized type, we may not detect that the destination type is an opaque, and therefore will call `type_of(opaque)` later on, which causes a cycle error -> ICE. Fixes rust-lang#120253
