Types obtained from typeck_results may contain aliases marked as rigid for their original typing environment. Make these aliases non-rigid before normalizing transmute types in TypingMode::Codegen. Also use TypingMode::Codegen in rustc_dump_layout, since opaque types may normalize to coroutines whose layouts cannot be computed in PostAnalysis mode. Add regression coverage for both cases.
